ERRORS IN THE CALIBRATION OF RADIANCE RADIOMETERS

摘要

A procedure has been developed which can be used to correct for. an error commonly encountered in the calibration of radiometers. If a radiometer designed for radiance determination is calibrated by means of a small source, loss of light due to imperfections in the optics can cause the radiometer to appear less sensitive than it actually is. Measurement of the angular response function provides a means for eliminating this error.
