Method and apparatus of digital calibration and position analysis of a radiant emission

摘要

Digital calibration and position analysis of impingement of a radiant emission on a multi-cell detector for calibration, including: directing radiant emissions to the multi-cell detector from a number of known origin positions and for each radiant emission from each origin position sampling the response of each cell, converting from analog to digital form the amplitude response of each cell; normalizing the digitized amplitude response of each cell; averaging the normalized digital amplitude response of each cell; determining from the average normalized digitized amplitude response and normalized digitized amplitude responses of each cell, the standard deviation value for each cell and the slope of the amplitude response of each cell; determining from the ratio of the slope and deviation values a weighting factor for the uncertainty of response of each cell at each origin position; determining with respect to each cell whether the origin position is to the left or right of that cell; and storing in one of a right and a left table for each cell a function of each origin position of emission, weighting factor, and normalized amplitude response for each cell for each origin position.
