摘要
介绍了采用距离选通技术进行非视域成像探测的原理,基于窄脉冲激光器和选通型成像器件搭建了非视域主动成像实验系统。以玻璃作为中介反射面,以黑白条纹靶板作为目标,对目标和周围环境处于不同光照情形时,系统的非视域成像效果进行测试。结果表明,基于距离选通的非视域成像技术是一种能够在不同光照条件下实现对视觉盲区进行有效观察的成像技术。
The principle of non-line-of-sight imaging technology based on rang gated is introduced in this paper,and the experimental system which is composed of short-pulse laser and imaging receiver with gated capability for non-line-of-sight imaging is constructed.In the experiment,the glass is selected as the intermdiary reflection plane and the board with white and black stripes is used as the target.The effect of non-line-of-sight imaging is tested under different conditions of background illumination on the target and surrounding.The results show that non-line-of-sight imaging technology based on rang gated is an effective method to observe the dead-zone under various background illumination.
