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.
