Abstract

This paper presents the process by which calibrations of radiometric detectors (either alone or as a part of electro-optical sensor systems) are conducted and applied to meaningful system applications. It is assumed that if a calibration is to be performed one desires that the calibration be "accurate". Accuracy always implies a comparison with a recognized standard. When one is dealing with a common property (say length) this may be straightforward. With a derived quantity (such as detector responsivity as an example) it becomes more difficult. There are two definitions for accuracy which are commonly used. One states that accuracy is "the absence of bias". Another view relates accuracy to the overall uncertainty of the measurement including a bounded but unknown bias. This paper is predicated upon the latter definition. Fig. 1 is used to explain why this point of view is taken.
