Title: Chandra Roychoudhuri: Innovator in Optical Radar Technology

Introduction

Chandra Roychoudhuri is a notable inventor based in Sandy Hook, CT (US). She has made significant contributions to the field of optical radar technology. Her innovative work has led to the development of a unique patent that enhances radar systems.

Latest Patents

Chandra holds a patent for a "Laser diode radar with extended range." This optical radar system incorporates a laser diode and an external cavity formed by a partial reflector. The system reflects a portion of the laser beam back into the diode while allowing another portion to pass out for backscatter from a target. The emission features a beat frequency that correlates with the target's velocity. A frequency chirp is introduced by mechanically oscillating the partial reflector, resulting in a modulation frequency that corresponds to the target's range. A photodetector and processor are utilized to determine both the velocity and range of the target.
