Paper Abstract

The two dimension performance model for low light level (LLL ) imaging systems will be studied and built in this paper, which is based and improved on the Johnson criteria and can also be used for thermal imaging systems. Two dimension threshold resolution angle and universal apparent distance detecting equation for LLL imaging systems will be given out. The new number of the resolvable circles across the target and the background for detection, recognition and identification will be put forward and some different definition for Johnson criteria will be discussed. Two dimension performance model is more accuracy and nearer practice than one dimension models especially for the case of the length is much larger than the width of the target and the background.
