Abstract: A system and method for standoff detection of explosives and explosive residue. A laser light source illuminates a target area having an unknown sample producing luminescence emitted photons, scattered photons and plasma emitted photons. A first optical system directs light to the target area. A video capture device outputs a dynamic image of the target area. A second optical system collects photons, and directs collected photons to a first two-dimensional array of detection elements and/or to a fiber array spectral translator device which device includes a two-dimensional array of optical fibers drawn into a one-dimensional fiber stack. A spectrograph is coupled to the one-dimensional fiber stack of the fiber array spectral translator device, wherein the entrance slit of the spectrograph is coupled to the one dimensional fiber stack.

Abstract: A fixed grating, detector-array type analyzer (100) rapidly multiplexes multiple channels. The analyzer (100) comprises a light source (110), a detector array-type spectrograph (150) and an optical multiplexer (130). The multiplexer (130) can select from one of a plurality of channels. Further, the multiplexer (130) can convolute light passing through it with a reference spectrum for calibration and wavelength drift compensation. Rapid multiplexing is achieved using a fiber optic slit array (140) which ''perpendicularly multiplexes'' the plurality of channels.
