Paper Abstract

The threshold detectivity of I2-CCD is studied based on the new concept of TV signal modulation transfer (STF) and noise modulation transfer function (NTF). The image detective ability equation of I2-CCD is established using the STF and NTF, as well as the theory of image threshold detectability. The detectability of I2-CCD cameras under several different conditions are calculated according to the equation. The theoretical calculation results fit well the experiment results. After analyzing the theoretical results several means to improve detective ability of I2-CCD are available.
