Title: Richard R. Chang: Innovator in Infrared Imaging Technology

Introduction

Richard R. Chang is a notable inventor based in McKinney, TX (US). He has made significant contributions to the field of infrared imaging technology, holding 2 patents that showcase his innovative approach to solving complex problems in this area.

Latest Patents

One of Richard's latest patents is for an infrared chopper using binary diffractive optics. This method utilizes an infrared imaging system to produce an image of a scene. Actual infrared radiation from the scene is detected to form a biased signal representing the radiances of objects within the scene. The biased signal is diffracted by causing rays of the radiation to pass through an array of lenslets at angles deviated from their normal path. The array includes an infrared transmissive deformable film that retains a pattern stamped into it, which includes a plurality of the diffracting lenslets. The diffracted and defocused radiation is detected to form a reference signal. This reference signal is subtracted from the biased signal to obtain an unbiased signal, and an image is generated and displayed in response to the unbiased signal.
