Optical system of a scanning radiometer
Abstract
This paper describes the optical system of a scanning radiometer for measuring the weak radiation in the upper atmosphere in the presence of strong extraneous illumination by the sun and the underlying surface. The range of luminance levels, measured by the instrument, extends to 0.0001-0.001 nit.
