双通道接收的无扫描激光成像技术

比较了几种无扫描激光三维成像技术的优缺点，提出一种基于双通道接收的强度调制型无扫描激光三维成像技术，该技术具有成像速度快、精度高、可靠性好、距离远的特点。采用大功率脉冲激光器作为激光照射源，两路ICCD同时接收，双通道分光系统将接收回波分到两路ICCD，通过两路ICCD强度信息反演出目标各点距离信息。重点介绍了该项技术工作原理和实现方法，研制了原理样机，进行了成像实验，对成像结果进行了分析，实现了作用距离5.1 km、作用距离30 m时距离分辨率0.25 m的技术指标。

Scannerless laser imaging technology based on multi-channel receiving

The advantage and disadvantage of different scannerless three-dimensional laser imaging systems was compared, the intensity modulation scannerless three-dimensional laser imaging technology based on multi-channel receiver was proposed. The technology has the advantage of fast imaging, high precision, high reliability, long distance. The high power pulse laser as the illumination source, two ICCD received the echo from dual channel sub optical system at the same time, the distance information was analyzed through the ICCD intensity information. The technology principle and approach was introduced. The principle sample machine was designed, and on which the imaging experiment was carried out. The experiment result shows that the imaging range is 5.1 km, range resolution is 0.25 m when range is 30 m.
