Paper Abstract

An accurate method for measuring charge transfer efficiency (η) and photoresponse nonuniformity (PRNU) of linear charge-coupled devices is developed. The apparatus is described. A finely focused light spot is adopted to irradiate each photosensitive element to get its response output signal. Data are collected automatically by scanning peak-searching and processed by linear best fitting. As examples, measurements for some types of devices are reported and factors influencing the results are discussed.
