摘　　要：研究目前文献中常见的１８种微光成像系统探测方程之间的内在联系和异同之处，分析论证各种阈值探测理论和探测方程存在的问题和不足。在此基础上，从人眼的视觉理论和阈值特性出发，建立微光成像系统新的阈值探测理论模型，并分别导出微光直视系统和微光电视系统的视距探测方程。应用所导出的理论公式计算的数据与各种实际系统的实测数据进行了比较，证明新的阈值探测理论和视距探测方程是正确可靠的，且具有很高的精度。The interconnection, similarities and differences between 18 detecting equations of LLL system, which are often met in many current documents are studied, and the existing problems and deficiencies in the different threshold detecting theories and detecting equations are analyzed anddemonstrated. On this basis, strating from the human-eye visual theory andthreshold property, a new threshold detecting theory model of LLL imaging system will be built, and apparent distance detecting equations for LLL directvisual system and LLL TV system will be derived respectively.The comparison between data calculated by the derived theory equations and the measured data from different Practical systems shows that the new threshold detecting theory and apparent distance equations are correct and reliable, and of very high accuracy.
