Abstract

Applying a spectral radiometer system to the broadest range of field measurements requires achieving maximum sensitivity and maximum spectral resolution over a broad band of wavelengths. A survey is made of methods of accomplishing this goal by conventional techniques and it is concluded that this requires the use of ponderous methods involving optical-mechanical control of the optical paths of multiple detectors and complex data processing to remove the effects of varying spectral sensitivity. The use of microprocessor control is surveyed and its application to specific radiometric processes is described in detail. Examples include the use of microprocessor control to switch the output of a sandwich radiation detector together with control of a spctral filter so as to use the most favorable detector-filter combinations. Also described is how the microprocessor makes possible automatic gain control, data sample averaging and data normalization to effectively remove the effects of the natural non-uniform spectral response of high-sensitivity detectors. The paper gives examples of the application of the radiometer to a reflectometer, transmissometer and other uses.
