Multidimensional integrated imaging for precision laser processing

Abstract

Computational illumination using a programmable LED array is a powerful, simple, and inexpensive method to enhance microscopy. Techniques like differential phase contrast and Fourier ptychography have been demonstrated for 2D and 3D enhanced imaging. In this work, we utilise these techniques for quality control, monitoring and feedback control of precision laser processing (PLP) processes. This approach benefits from no moving parts and easy integration, relying on computational methods and computer vision techniques. By merging theoretical development with practical application, we showcase the effectiveness of these techniques in industrial settings to suit several laser manufacturing needs.

Dr. Álvaro Fernández Galiana is a postdoctoral research fellow at the University of Oxford's Department of Engineering Science in the Dynamic Optics and Photonics Group. His work centers on designing and implementing precision opto-mechanical instrumentation for applications in quantum optics and medical device engineering. Currently, his research focuses on two primary areas: developing spectroscopy-based biosensing technologies for universal health population screening and advancing optical microscopy techniques for monitoring and controlling precision laser processing. Previously, Álvaro was a Schmidt Science Fellow (2021) and an honorary research fellow in the Stevens group at Imperial College London, where he also worked on spectroscopy-based biosensing. He earned his Ph.D. in Mechanical Engineering from the Massachusetts Institute of Technology (2021), conducting his doctoral research at MIT's LIGO laboratory on precision optomechanical instrumentation.
