HAND-HELD MULTISPECTRAL RADIOMETER FOR REMOTE SENSING

摘要

A hand-held, battery powered instrument for the determination and recording of the intensity of radiation emitted or reflected by a target in the field in spectral bands from 400 nm to 12 micrometers. Two fields of view, typically 20 DEG and 1 DEG , are provided. The pointing accuracy is 0.1 DEG or better. Multiple detectors are controlled by a single shutter. Gain and zero controls are preset, the whole spectral band is sampled in 4 seconds, and the results stored. They are later called up and shown on a liquid crystal display digitized to 9999.
