Figures of Merit to Characterize Integrating Image Sensors: A Ten-Year Update.

摘要

A ten-year update is presented on performance criteria and measurement techniques to evaluate integrating image sensors. The integrating image sensor has an irradiance sensitive focal plane that continuously monitors the field of view and an electronic mechanism that sequentially reads out the integrated signal on each resolution element. Ten years ago, camera tubes were the integrating imagers of interest; today, staring focal plane arrays have supplanted camera tubes as integrating imagers. The adaptability of the 1978 figures of merit to the new staring devices is reviewed and, when indicated, the figures are modified. Keywords: Camera tube performance; Image sensors; Image standards; Imagery figures of merit; Television performance standards; Vidicon standards. (JHD)
