Abstract
A radiation detection system for use in the visible and near infrared reg which is capable of detecting and recording extremely weak laser pulses in the few nanoseconds range. The system receiver can be directed towards strong radiation sources, such as the sun, without changing the receiver or recording unwanted information. The detection system discriminates between various selected laser sources wavelengths and is comprised of optics, detector, electronic hardware, microcomputer, and signature analysis algorithm.
