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.
