All the caliber proofreading systems null for visible infrared radiometer

摘要

PURPOSE: To make calibration of the light quantity in a visible infrared radiome ter with full bore of the light receiving system through composite usage of various light sources ranging from visible to infrared ray. ;CONSTITUTION: The measuring light 102 and calibration light 103 including three calibrating beams (a, b, c) are put in parallel beams by a reflex mirror 3 as three different light sources are installed in the light source part 5 arranged at the focus of the reflex mirror. Generally the calibration light is a little dislocated from the parallel beams due to different positions of the light source, but can be led to a radiometer optical part 4 by changing the rotaional angle of the calibration light incident to a scanning mirror 1.;COPYRIGHT: (C)1994,JPO&Japio
