Abstract

Superposition and calibrated attenuator methods are often used to determine the nonlinearity of photodetectors. A variation of these methods is described and applied to the calibration of optical pyrometers. This scheme allows a considerable reduction in the time needed for the measurement because only three independent sets of measurements are required, without any need to realize an accurate radiance scale on the sources.
