G&H's Senior Vice President of Aerospace & Defense, Frank Weiss, and Regional Product Manager of US/NA Precision Optics, Adam Morrow, were consulted and quoted in the recently published article of the April 2023 issue of Photonics Spectra magazine. The article "Smaller Optical Gyroscopes Navigate into Broader Markets," discusses how integrated photonics are shrinking optical gyroscopes and opening doors to the UAV middle market for smaller aerial platforms. Current trends are driving the need for unmanned aerial vehicles (UAVs) that are smaller, able to operate in environments with limited or no GPS guidance, and capable of delivering enhanced pointing accuracy for mapping applications. This is fueling the drive to reduce the dimensions of ring-laser and fiber optic gyroscopes to a fraction of those currently on board the Global Hawk. In some cases, this means fabricating smaller components for RLGs or replacing parts of fiber optic gyroscopes (FOGs) with photonic chips or hollow-core fibers. The use of integrated photonics will expand opportunities in the UAV market, with potential applications in agriculture, package delivery services, and remote monitoring and inspection. The Sagnec effect The Sagnac effect is used in optical gyroscopes and ring laser gyroscopes (RLGs) to measure angular velocity and orientation. Optical gyroscopes use fiber optic coils while RLGs use lasers and mirrors. Frank Weiss comments, “One of the critical requirements of UAVs is operation in GPS-deprived environments. This is most prevalent in military applications but can be useful in autonomous terrain mapping as well. In this application, it is critical to maximize the time of flight available under autonomous navigation. Working from a defined reference and high- accuracy starting point and handing off these precision coordinates to an autonomously guided platform, a high-stability, low-drift gyro will perform better and for longer periods of time. RLG is well suited for this.” Miniaturization RLG sensors are more durable against shock, vibration, and temperature compared to FOG systems. However, RLG technology requires mechanical dithering that can generate noise and unwanted signatures. Miniaturization of RFG components is improving SWaP-C and making it competitive with FOG devices, but further reductions in size and power may depend on advancements in RLG substrates. Adam Morrow explains, “The ruggedness of the optics within RLG devices is further aided by coatings designed to survive extreme environmental conditions, as well as by substrate materials with high mechanical stability. Size limits are a function of the overall optical system design of the RLG, but weight reductions can be made in the frame. In doing so, care must be taken to not impair the mechanical stability of the RLG. Outside of the precision optical components, cost, and power consumption reductions can be looked at for the laser source as well. The full article, written by James Schlett, Contributing Editor, can be found in the April 2023 issue of Photonics Spectra magazine or you can read the full publication on the Photonics.com website. Our ring laser gyroscopes (RLG) are deployed in commercial aircraft, missiles, satellites, and other military vehicles. Vertical integration enables us to supply the entire ring laser gyroscope components package: RLG frame and optical components. Our integration of capabilities delivers superior performance and streamlines sourcing.

In the rapidly evolving field of counter-Unmanned Aircraft Systems (C-UAS), the choice of optics plays a crucial role in ensuring effective detection and response. Shortwave imaging systems offer several advantages over visible and midwave imaging systems for daytime range detection, making them a critical inclusion in any multi-sensor C-UAS payload. In this discussion, we will explore why shortwave zoom lenses are exceptionally well-suited for countering the emerging threats posed by unmanned aerial systems and why G&H StingRay's FireAnt series is uniquely positioned to address that need in particular. General Advantages of SWIR for Daytime Range Detection and Tracking: Atmospheric Transparency: Shortwave infrared (SWIR) light experiences less atmospheric absorption and scattering compared to both visible and midwave infrared (MWIR) light during the day. This means that SWIR imaging systems can see through atmospheric disturbances, such as haze, dust, and fog, more effectively. This improved visibility is crucial for long-range detection during daylight hours. Solar Glint and Background Radiation: SWIR sensors are less susceptible to solar glint, the reflection of sunlight off objects, compared to MWIR sensors. MWIR sensors can be overwhelmed by the bright background radiation from the sun, which can limit their effectiveness during the daytime. SWIR sensors, on the other hand, can operate more effectively in the presence of strong sunlight, allowing for better range detection. Reduced Heat Signature: Unlike MWIR systems, SWIR imaging systems do not detect thermal radiation. This means that they are less affected by variations in temperature and do not suffer from the same challenges as MWIR systems when it comes to distinguishing between objects with similar thermal profiles. In daytime conditions, this can lead to improved accuracy in range detection. Improved Target Discrimination: SWIR imaging systems often provide better target discrimination and identification due to their ability to detect variations in material properties. This can be especially important during daytime operations when identifying specific objects or targets is critical. That's a pretty compelling argument for the incorporation of SWIR in C-UAS generally, but not all SWIR imaging systems are created equal and G&H StingRay has long been the industry's leader in this space. That's why we confidently announce the newest addition to the FireAnt series, our ruggedized F/6 80-800mm zoom lens. Designed for direct compatibility with 5µm and 10µm SXGA image formats, the 80-800mm FireAnt is a testament to a performance-first design methodology that incorporates SWIR specific materials and anti-reflection coatings, an approach yielding the best resolution and transmission available in a COTS SWIR imaging system. Many commercially available visible and shortwave zooms allow for a reduction in aperture as you move from the wide field to narrow field positions, whereas every FireAnt lens offers a constant aperture through its respective zoom range, a feature that lends itself directly to C-UAS applications: Advantages of a Constant Aperture for C-UAS: Target acquisition and tracking: It's crucial to quickly acquire and track threats. A zoom lens with a constant aperture allows for seamless zooming without changes in exposure, which aids in maintaining a clear and consistent view of the target. This is particularly important in dynamic situations where rapid adjustments are necessary. Depth of field control: The ability to control depth of field can help isolate and focus on specific subjects or areas of interest, enhance object recognition, or aid in target identification. A constant aperture zoom lens allows for consistent depth of field control throughout the zoom range, ensuring clear and sharp focus regardless of the focal length used. Consistent power density: A constant aperture zoom lens helps maintain a consistent power density when imaging a laser beam throughout the zoom range. This is important for shortwave targeting applications where maintaining a specific power density is crucial for effective operation. Consistency in power density ensures consistent performance and reliable results across different zoom levels. G&H | StingRay - Industry Leading High-Performance SWIR: In conclusion, as the field of counter-Unmanned Aircraft Systems (C-UAS) continues to evolve, the choice of optics becomes paramount for effective detection and response. Shortwave imaging systems, particularly SWIR zoom lenses, offer distinct advantages over visible and midwave systems, especially during daytime range detection. They excel in atmospheric transparency, are less susceptible to solar glint and background radiation, exhibit a reduced heat signature, and provide superior target discrimination. Among SWIR zoom lenses, G&H StingRay's FireAnt series stands out as an industry leader. The latest addition, the ruggedized F/6 80-800mm zoom lens, is designed for optimal performance, incorporating SWIR-specific materials and anti-reflection coatings. Its constant aperture feature enhances target acquisition, depth of field control, and power density consistency, making it an ideal choice for C-UAS applications. G&H StingRay's commitment to innovation continues to address the evolving challenges posed by unmanned aerial systems, ensuring reliable and effective solutions in the fight against emerging threats.

Challenging times call for strongly innovative solutions. In search of the next-generation armored fighter vehicle to complete the Main Battle Tank (MBT) request of the British Army, Rheinmetall Electronics UK (REUK) initiated a collaboration with G&H, to work on an integrated sighting system that excels at reconnaissance, surveillance, driver safety, and target acquisition. The optics and photonics industry leader has been awarded a £4.1M Challenger 3 contract to deliver a generational upgrade to the Embedded Image Periscope (EIP) system, which would integrate with the rest of the planned high-tech improvements. This would prove to be a bold project aimed at matching the overall strategic and technological leap planned for this British MBT. Dubbed “the eyes of the British Challenger 3”, the new EIP, developed and manufactured by UK-based G&H | Kent, integrates a combination of classic glass and digital display electronic periscope design. This fusion allows for a wider selection of views for the driver, eliminating unnecessary head position movements and periscope swapping. Equipped with “standalone” and “leave alone” day and night options, as well as a relaxed-view biocular for eye relief, the versatility of the EIP is expressed through its modular build. Respecting the high-precision environment in which the periscope technology needs to perform, its adaptability has been maximized to fit any necessary requirements from the crew. A game-changing element brought in by the G&H team in the product design process represents the EIP’s reversionary mode. A strong feature according to the feedback retrieved from various UK MoD trials, this functionality addresses high-risk cases, as explained by Peter Kean, G&H’s Innovation Unit Director of Optics & Photonics: “In the event that a vehicle loses all its power, you can’t use your displays or your situational awareness cameras that feed into this system. But the driver still needs to be able to see, to exit the threat in the environment. Through this system, a combined glass and electronic periscope, with the flick of a switch, you are just looking out of a glass periscope. So, in that ultra-threat scenario, you just flick the switch and drive.” Another key feature in the design of Challenger 3 is its immersive and immediate communication capability. As stated by former UK defense secretary Ben Wallace, “what you will see is a far more integrated vehicle”.1 G&H’s approach to the technological development of the EIP is aiming to enhance precisely this quality of the new MBT through its digital connectivity with the Spectre camera system. This electronic feature includes both a day and a thermal imaging camera, plus an overlay of the two. As such, crew members save precious seconds in reaction time when needing to secure a mission. The focus placed on EIP solutions for armored fighting vehicles (AFVs) has to be translated into battlefield fluency. In this case, the new Challenger 3 periscope underwent a set of customization stages in order to respond seamlessly within REUK’s Trailblazer Driver Vision System. Richard Streeter, REUK’s Managing Director, appreciated the end result: “We are very pleased to have G&H on-board, delivering this important component into the Challenger 3 program. The display system is critical; delivering front and rear views from the Trailblazer camera modules, enabling the driver to carry out the platform mission. The G&H solution allows a comfortable operating view suitable for long mission periods, while minimizing the driver’s eye strain. The G&H technology is unique and the team at St. Asaph and Ilminster are experts in delivering complex electro-optic solutions.” When envisioning the tank that would represent the United Kingdom’s armored capability, the expectations were set very high.
