Title: The Innovations of William J Green, Jr.
Introduction
William J Green, Jr. is a notable inventor based in Vernon, CT (US). He has made significant contributions to the field of optical radar technology, holding two patents that showcase his innovative spirit and technical expertise. His work primarily supports the US Government as represented by the Secretary of the Army.
Latest Patents
One of Green's latest patents is the "Injection Controlled Laser Transmitter with Twin Local Oscillators." This invention involves a heterodyne CO.sub.2 optical Doppler radar that utilizes a ring-type traitter laser and twin local oscillator lasers. These lasers are automatically controlled to operate at a difference frequency equal to the intermediate frequency of the radar, which may be in the VHF band. The output of one of the twin lasers is injected into the transmitter laser for stabilization, while the other is heterodyned with the received target return signals to form the radar's intermediate frequency signal.
Another significant patent is the "Programmable Scanner/Tracker." This invention is designed for airborne obstacle avoidance optical radars operating in the infrared region. The radar beam is scanned by passing it through a pair of in-line rotating optical wedges, which are transparent to infrared radiation. These wedges are separately driven by servo systems, including hollow shaft torque motors, and a high-resolution, low-backlash shaft position encoder is utilized to enhance the tracking accuracy.
