Title: The Innovative Contributions of Bret Whiteside

Introduction

Bret Whiteside is a prominent inventor based in Gilroy, California, known for his significant contributions to optical inspection systems. With a total of 15 patents to his name, he has made remarkable advancements in the field of polarization filtering.

Latest Patents

Whiteside'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 the system also incorporates a linear polarizer to filter out the linearly polarized light. The second patent similarly focuses on an optical inspection system that employs gratings on a reflective substrate to achieve the same polarization conversion, enhancing the efficiency of optical inspections.
