Abstract
A sensor having an input to an interferometer. The input may receive emissions from a detected fluid. The output of the interferometer may be focused on an array of light detectors. Electrical signals from the detectors may go to a processor. The output of the processor may include a spectrum of the detected fluid. Also, the identity of the fluid may be determined.
