Title: The Innovations of Charles L Woods

Introduction

Charles L Woods is a notable inventor based in Stow, MA (US), recognized for his contributions to optical imaging technologies. With a total of 15 patents, Woods has made significant advancements in the field, particularly in methods for recovering distorted optical images.

Latest Patents

Woods' latest patents include the "Pseudo deconvolution method of recovering a distorted optical image." This innovative method involves a first lens that produces a Fourier transform of the distorted optical image at the Fourier transform plane. A phase-encoded filter is positioned at this plane, along with a second filter that has a transmittance statistically similar to the reciprocal spatial frequency spectrum of the distortion function. This setup allows for the production of an intermediate signal, which is then Fourier transformed by a second lens to recover the optical image with a significantly reduced degree of distortion. Another notable patent is the "Incoherent erasure joint transform correlator." In this invention, a holographic grating is written into a photorefractive erasable holographic member. A light beam with a specific wavelength, which includes the joint power spectrum of a pair of joint images, is directed at the photorefractive member to partially erase the grating. The phase conjugate signal from the partially erased grating is then read out and Fourier transformed to produce the correlation output spots.
