Abstract:

A multichannel optical detection system MODS for use in the detection of spectral information contained within a short pulsed light event has been developed. The system is based upon a technique which employs a series of fiber-optic waveguides to separate temporally the various spectral components of a light pulse, thus allowing spectral information to be detected by one or a relatively small number of photomultiplier tubes PMT. The impetus for development of this technique was the prospect of a cost-effective multichannel optical detector having the speed, sensitivity, range, and other advantages inherent in photomultiplier detection. A small-scale version of this system consisting of 12 discrete channels has been assembled and operated. This 12-channel prototype was used to demonstrate the feasibility of the detection-system concept. Knowledge gained in the development of this system has been applied to the design of a practical-scale system consisting of 100 separate channels.
