微光夜视仪的作用距离估算与仿真

Estimation and simulation of operation range for low-light-level night vision device

微光夜视仪是一种重要的夜视光电器材,而作用距离是其重要的性能参数之一。本文针对微光夜视仪的视距估算,分析比较了极限分辨率曲线法、光子受限法和修正的光子受限法等三种方法的视距估算原理,并利用VB语言编程开发了视距估算软件。实验结果验证了微光夜视仪作用距离估算模型的有效性。

Low-light-level（LLL） night vision device is an important optoelectronic equipment, and the operation range is one of its important performance parameters. Aiming at the estimation of operation range for LLL night vision sys- tem, three estimation methods are analyzed, which are limiting resolution curve method, restricted photon method and improved restricted photon method. The view range estimation software was programmed with VB language. The experi- mental results verifies the effectiveness of the estimation model of operation range.
