摘　　要：在对各种阈值探测理论和视距探测方程进行深入研究分析的基础上 ,从人眼阈值特性和微光视觉理论出发 ,建立微光夜视系统新的阈值探测理论模型 。Based on the photon noise fluctuation theory,linear filter theory,the threshold characteristics and visual theories of the human eye, the new threshold detection theory and apparent distance detecting equations for LLL (low light level) imaging system will be established and derived in this paper.
