Abstract

The design and operation of an imaging Michelson interferometer-spectrometer used for near-infrared (0.8 μm to 2.5 μm) spectral imaging is reported. The system employs a rapid scan interferometer modified for stable low resolution (250 cm-1) performance and a 42 element PbS linear detector array. A microcomputer system is described which provides data acquisition, coadding, and Fourier transformation for near real-time presentation of the spectra of all 42 scene elements. The electronic and mechanical designs are discussed and telescope performance data presented.
