Doubly multiplexing dispersive spectrometer.
Abstract
Description of a spectrometer that incorporates 19 entrances and 19 exit slots. The instrument's dual capability to perform either one-dimensional imaging or alternately to give a spectrum with a high SNR over the entire source is shown. The instrument operates in the Littrow mode at f/8. The slot width and length for each mask are 0.625 and 3.5 mm, respectively, giving a total aperture length of 12.1 mm. The corresponding resolving power at 1.7 microns is 230.
