Abstract
A spectroscopic system having a coded aperture as a gating device. Light of a Raman scattering may enter the system and encounter a mask gate. The mask may have a matrix of micro mirrors some of which pass light on to a diffraction grating when the gate is on. Some of the mirrors will not pass on light thereby resulting in coded light to the grating. If the gate is off, then no light is passed on to the grating. The grating may pass the coded and spectrally spread light on to a detector array. The array signals representing the light on the array may go to a processor so one can obtain information about the target that emanated the Raman scatter when impinged by a light beam.

18. A method for spectroscopy comprising:
-
receiving scattered light; focusing the light on a coded aperture gate; opening the gate for light that is Raman scattered light from a sample impinged by light from a light source; closing the gate as soon as the Raman scattered light is no longer received; and letting the light be directed by the open gate to a diffractive device to be diffracted according to wavelength on a detector array. - View Dependent Claims (19, 20)
