ABSTRACT:
A programmable substance detector includes a light source, a sample cell, a programmable diffraction grating positioned to receive light from the light source and to direct diffracted light to the sample cell, and a detector associated with the cell to detect a match between a characteristic of the diffracted light and a corresponding characteristic of a substance within the cell.
