Patent ID: 7737399

Claim:
An electronics analog Mueller matrix system (AMMS) comprising: an infrared photopolarimetric-based differential-absorption Mueller matrix spectroscopy (DIAMMS) chemical and biological remote sensor comprising a photoelastic-modulation engine and a computer; a reference synthesizing module operatively connected to said remote sensor, said reference synthesizing module comprising circuits generating two primary and six overtone pure coherent sinusoidal frequencies to serve as reference waveforms; a scattergram intensity regulation and control module operatively connected to said reference synthesizing module, said scattergram intensity regulation and control module comprising an electromechanical system that automatically maintains constant magnitude of optical backscattering intensity as said photoelastic-modulation engine permutes to one of a plurality of configurations; a phase correlation module operatively connected to said scattergram intensity regulation and control module, wherein said phase correlation module provides a plurality of Mueller (M) matrix elements as analog signals per fundamental/overtone frequency assignments in scattergram voltage waveforms detected by said remote sensor; a data digitization and computer interface module operatively connected to said phase correlation module, wherein said data digitization and computer interface module digitizes the Mueller matrix analog signals from said phase correlation module and transmits the digitized signals to said computer of said remote sensor; and a graphical user interface (GUI) system operatively connected to said data digitization and computer interface module, wherein said GUI system controls said remote sensor.
