激光测距机低温测距性能实验设计

Experiments on testing range-finding properties of laser range finder under lower temperature circumstance

针对激光测距机 -4 0℃工作温度性能测量要求 ,提出在常温下对低温激光测距机测距性能检测的方法 ,采用低温试验箱安装可加热的导电膜光学观测窗设计方案 ,叙述了实现激光测距机低温测距性能检测的初步实验结果和讨论 ,从而保证激光测距机出厂前的直接检测及标定。

The experimental designs and the characteristics of a laser range finder under -40℃ circumstance were investigated with ITO optical windows heated to keep observation from dew or hoarfrost at room temperature. Primary experimental results and data of laser range finder in low temperature circumstance were accumulated and discussed. To meet the demands of the performance inspection of the laser range finder in working condition, the designs of ITO windows set up on a low temperature cabinet, are used to confirm the quality inspection and calibration of the laser range finder before its leaving from factory.
