ABSTRACT:
A sensor containing a beam emitter that emits a first beam having laser, a beam-splitting interferometer and an array detector, wherein the first beam is to strike a sample that produces a second beam comprising a Raman signal, the beam-splitting interferometer is to create a phase delay in the second beam, and the array detector comprises a plurality of detectors is disclosed. The sensor could be used for spectroscopic detection of a sample by generating a first beam comprising laser, striking the first beam to a sample to produce a second beam comprising a Raman signal, creating a phase delay in the second beam and detecting the Raman signal of the second beam. The uses of the sensor include detection of biological and chemical warfare agents, narcotics, among others for homeland security.
