Abstract

A multispectral scanner is designed for acquisition of the multispectral spatially matched quantitative information on both reflectance and emittance of on-ground objects. Mechanical scanning is used. Six spectral channels are operable in the range of 0.4 - 12.5 micrometer. All the channels are provided with the removable sets including four optical filters for each channel. Switching or change of the filters can be performed by the remote control unit. The channels are designed to match spectral ranges that are similar to those which can be found in space sensors for TM-84, ETM, SPOT, NOAA. The digitized field of view is 51.2 degrees. The instantaneous field of view for each channel is 5 minutes. The precision of optical matching for all the channels is no worse than 1/3 of pixel. The selectable scan rates are 18, 36, and 72 scans per second. In the channels of the range 0.43 - 0.9 micrometer the multispectral scanner ensures the values of signal/noise ratios 80 - 200; within the range of 1.5 - 2.5 micrometer signal/noise ratios are no less than 100, and within the range of 8 - 12.5 micrometer no less than 25.
