Dot Projector Modules for Depth Sensing
Coherent Corp. (NYSE: COHR), a leader in optical sensing for consumer electronics, today announced the introduction of dot projector modules for depth sensing in consumer electronics, robotics, and autonomous vehicles. As the number of use cases for 3D cameras continues to increase, the demand is growing rapidly for sensor technology that can be configured for a wide range of applications and optimized for performance and cost. To meet the growing demand, Coherent is introducing dot projector modules based on 940 nm vertical-cavity surface-emitting lasers (VCSELs) with designs ranging from 600 to 13,000 dots, to match various depth range and spatial resolution requirements of spot-assisted time-of-flight (TOF) 3D cameras. Dot projector modules from Coherent enable customers to design cameras that capture an entire scene at a broad angle and extended depth range even in bright outdoor lighting conditions, all while maintaining low power consumption. The miniature dot projector modules are based on surface-mount technology (SMT) for seamless integration. “Our customizable dot projector module is a breakthrough product that our customers appreciate for its ability to project a sharp dot pattern with high contrast ratio, enabling excellent depth resolution at the system level,” said Dr. David Ahmari, Vice President & General Manager, Optoelectronic Devices & Modules Business. “This product lowers the burden of optics design and system integration, which shortens time to market. By leveraging the economies of scale of our vertically integrated U.S.-based 6-inch laser technology platform that has delivered more than 200 billion VCSEL emitters to date, we also offer our customers scalability, supply-chain security, and leading quality.” Each dot pattern is configured to match a specific TOF depth sensing application simply by optimizing the optics design for the required number of dots and field of illumination (FOI). The dot projectors offer a high contrast ratio with FOI from 60°x45° to 130°x110°, including 100°x20° to enable high image contrasts for vacuum cleaner robots working over highly reflective floor surfaces. The dot projector modules can be combined with the flood illuminator modules from Coherent for long- and short-range imaging. Coherent also offers a broad portfolio of components for sensing, including semiconductor laser diodes in the near-, shortwave-, and mid-infrared wavelength ranges; photodiodes; diffractive meta-optics; and laser driver integrated circuits, as well as optoelectronic assemblies and illumination modules. Coherent will showcase its broad range of products and innovations for sensing at Photonics West 2024 in San Francisco, Jan. 30 to Feb. 1, Booth #4805.

Coherent Corp. (NYSE: COHR), a leader in semiconductor lasers for depth sensors, today announced the introduction of an illumination module platform for short- and mid-range light detection and ranging (LiDAR) in automotive safety and robotic vision in industrial applications. The growing adoption of advanced driver assistance systems (ADAS) in vehicles and of depth sensing in industrial robots is accelerating the demand for compact and flexible LiDAR systems that perform efficiently and reliably, even in the most extreme environments. Using eight 940 nm vertical-cavity surface-emitting laser (VCSEL) modules, Coherent has demonstrated a solution with several selectively addressable horizontal slices of the field of illumination (FOI). In addition to offering a compact form factor and excellent power conversion efficiency, the module is a much lower-cost alternative than using large addressable VCSEL arrays. Coherent has a demonstrator available for its customers to explore multiple VCSEL module positioning configurations and scanning algorithms for various depth sensing modalities and types of scenery. “A powerful aspect of the module platform is the ability to customize an optimized solution for use cases requiring up to 30 meters of depth sensing in bright daylight. Our illuminators exceed 30% total power conversion efficiency and have a compact footprint, only about a third of the size of a credit card,” said Dr. David Ahmari, Vice President & General Manager, Optoelectronic Devices & Modules Business. “To achieve this breakthrough in efficiency and size, we are leveraging our state-of-the-art five-junction VCSEL technology that enables each illuminator module to achieve up to 200 W of output power. Our demonstrator is available for customers to evaluate and better envision the expanded universe of applications enabled.” Customers of Coherent will be able to adjust the duration of the driving pulses to achieve both short- and mid-range LiDAR sensing. The FOI slices are dynamically selectable depending on the number of VCSEL modules and the order in which they are scanned. A voltage supply of only 21 V is required, which is much lower, and therefore more efficient, than existing LiDAR technology. Coherent offers a broad portfolio of active and passive products for LiDAR designs. The portfolio of active devices includes VCSELs, edge-emitters, laser bars, frequency-modulated continuous wave (FMCW) sources, and pulsed fiber-based sources. The portfolio of passive devices includes laser optics, polygons, galvo mirrors, lenses, ultra-narrowband filters, wide-incidence-angle mirrors, gratings, and thermoelectrics. Coherent will showcase its broad range of products and innovations for sensing at Photonics West 2024 in San Francisco, Jan. 30 to Feb. 1, Booth #4805.
