Abstract

Multiband capability for Earth-imaging systems using linear array detectors operating in the push-broom scan mode have been limited to six to seven spectral bands with present state-of-the-art Multispectral Linear Array (MLA) system designs. With the desire to have Earth-imaging systems that offer many more spectral bands (25, for example), Earth-imaging push-broom spectrometer designs have been developed that spectrally disperse the incoming light by using a grating or prism and thereby creating a multiplicity of spectral bands that are sampled by an area array detector. The spectrometer designs, as well as some of the MLA designs, offer inherent spatial coregistration among the spectral bands--a very desirable feature. A problem with the spectrometer designs is that they are complex, inefficient, and costly. The problem with the linear array detector system designs has been that, until the advent of the Multiband Selection Device (MSD), they were limited in the number of spectral bands that could be sampled. When using this device, an almost unlimited number of spectral band combinations can be offered with Earth-imaging system designs using state-of-the-art optics and linear array detectors. This paper compares the complexity of a spectrometer design with a beam-splitter/MSD system design, describes different concepts that were examined for providing a multiband selection capability for MLA instruments, and describes in detail the successful development and test of the Multiband Selection Device.
