A study of threshold LLL-CCD cameras
A concept of TV-signal to noise ratio transfer function (SNTF) is proposed in paper, and a deterotive equation is established based on the SNTF. Theoretical calculated resulte well coordinate with the experimental results. Values of detectivity of LLL-CCD cameras under several different conditions are calculated based on the equation with the aid of computer. After analysis of the results, some ways of improving detective ability of LLL-CCD are proposed.
