Title: Innovations by Inventor Chong Shen
Introduction
Chong Shen is a notable inventor based in San Jose, California. He has made significant contributions to the field of optical inspection systems, holding two patents that showcase his innovative approach to technology.
Latest Patents
Chong Shen's latest patents include "Single-material waveplates for pupil polarization filtering" and "Reflective waveplates for pupil polarization filtering." The first patent describes an optical inspection system that utilizes single-material gratings to convert the polarization of light scattered from a target. This system transforms elliptical polarization, which varies spatially across a collection pupil, into a linear polarization that is uniformly oriented. The gratings have phase retardation that varies in accordance with the elliptical polarization, and a linear polarizer is included to filter out the linearly polarized light. The second patent similarly describes an optical inspection system that employs gratings on a reflective substrate to achieve the same polarization conversion, ensuring effective filtering of linearly polarized light.
