电视成像系统作用距离分析

The Research for Effective Distance of TV System on a Theodolite

光电经纬仪是靶场重要的测轨设备,经纬仪的电视系统作用距离是其关键指标之一,在系统设计过程中,必须给予充分论证。详细分析了影响电视跟踪系统作用距离的因素,分析了目标、天空背景在电视像面的照度和对比度,建立了标准大气条件下,电视系统作用距离的数学模型。

The optoelectronic theodolite is an important testing equipment to track targets.The effective distance of TV system is one of it's key performance index which must be analyzed and testified when the thodolite is designed.It discusses the factors that affect the effective distance of TV,analyzes the lum and contrast of targets and sky background on the imaging surface of TV.A mathematic model of effective distance of TV under the standard air condition is also constructed.
