System and method for remote sensing and/or analyzing spectral properties of targets and/or chemical species for detection and identification thereof

A system for remote sensing and analyzing spectral properties of at least one target and/or chemical species, said system comprising:

• a light gathering device that collects, focuses, and directs incoming radiation emitted and/or absorbed and/or scattered by the target and/or chemical species to be analyzed to one of a plurality of detectors;
• at least one spectrally discriminating optical element in front of at least some of said detectors for spectrally resolving said collected radiation;
• said detectors, in relative movement with said light gathering device, producing an output signal;
• a driving device to produce said relative movement between said light gathering device and said detectors;
• a device or method to monitor phase and frequency of the relative movement;
• and
• a demodulation device, synchronous with said driving device, to demodulate said output signal produced by said detectors.

A method for remote sensing and analyzing spectral properties of at least one target and/or chemical species, said method comprising:

• collecting and focusing incoming radiation emitted and/or absorbed and/or scattered by the target and/or chemical species to be analyzed, said collecting and focusing being conducted from a gathering location;
• directing said focused radiation, said directing being conducted at a directing location;
• spectrally analyzing said collected radiation at a spectral analysis location, said spectral analysis produces spectral signature that can be used to identify target;
• detecting said directed and spectrally analyzed radiation at a detecting location, wherein said directing location and said detecting location is in relative movement from one another, said detection producing an output signal;
• monitoring the phase and frequency of the relative movement;
• and
• demodulating said output signal.
