ABSTRACT:
An fixed grating, detector-array type analyzer rapidly multiplexes multiple channels. The analyzer comprises a light source, a detector array-type spectrograph, and an optical multiplexer. The multiplexer can select from one of a plurality of channels. Further, the multiplexer 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 which "perpendicularly multiplexes" the plurality of channels.
