US 5,708,503 A · Panoramic infrared-imaging spectroradiometer with reverse phase modulation beam broadcasting

Abstract

A spectroradiometer for analyzing chemicals located within a panorama comsed of hyperboloid mirrors for directing light received from the panorama through a collimator and via an interferometer to an array of detectors, the signals from which are subjected to parallel discrete Fourier transform and parallel spectra pattern recognition systems. Transmissions of data is achieved by using an interferometer having modulated photoelastic modulators positioned between linear polarizers, directing laser light through the interferometer to the hyperboloid mirrors and providing a receiver comprised of a linear polarizer, a detector, a plurality of band pass amplifiers, and a processor for recognizing the different patterns in the output of the amplifier that result from rotating at least one of the photoelastic modulators and polarizers to a different position.
