Real Time Video Transfer Using Multiple Quantum Well Retromodulators

Abstract

This paper is an update in the progress of the development of NRL's Multiple Quantum Well retromodulators for compact, low power communications. We report results for data-in-flight on a small unmanned aerial vehicle at up to 5 Mbps in preparation for real-time video transfer using an array of devices. This data was taken at Chesapeake Bay Detachment. We also report transference of color video using wavelet compression at 15 and 30 frames per second. at 4 to 6 Mbps in lab. at eye safe intensity levels. The unit is a cornercube modulator using a 980 nm shutter. A five-element array was used for the data-in-flight. First results of our 1550 nm devices are also presented as is progress in a "Cats Eye Retromodulator".
