一种红外引导激光指向双模复合探测技术研究

Research on Dual-Mode Hybrid Detection Technology Using Laser to Point Directed by Infrared Camera

随着红外光电系统由扫描型发展为凝视型,搜索范围大大增加,但仅得到目标的二维信息,如能与激光主动探测结合,得到角度-角度-距离的三维信息,可实现两者优势互补。提出了一种基于压电倾斜镜(PFSM)的具有指向功能的激光主动探测技术,与凝视型红外相机实现双模复合探测,对目标进行精密跟踪。对其视场、线性度进行了分析和系统测试,所得结果与计算结果相符。

With the development from scanning mode to staring mode, infrared radiation （IR） optoelectronic system can realize scouting in large field. But it can only get the two-dimensional information of target. If combined with laser active detection, three-dimensional information of angle-angle-distance can be got, which are mutually complementary. A laser active detection technology with pointed function based on two-dimensional piezoelectric fast- steering mirror （PFSM） is proposed and discussed, which realizes the IR imaging/ladar dual-mode detection to track the target with high precision. The field of view and its linearity are analyzed and tested, which accord well with the calculation result .
