设计开发了一套基于成像法的中波红外激光远场功率测量系统，给出了成像法测量远场激光功率密度分布的基本原理。利用漫反射靶板将激光的功率分布信息采集至中波红外热像仪，并在靶板的特征位置上安装功率探测器，将光斑图像灰度信息与激光功率探头所测的实际功率值进行信息融合，得出灰度值与功率密度的映射关系，进而推测激光远场功率密度分布。此系统测量误差小，且系统简单、可靠，适于各种条件下的中波红外激光远场功率密度测量，可满足目前大功率红外激光干扰装备的测量需求。

A set of Mid-IR laser far-field power measurement system based on imaging method is designed and developed. The basic principle of imaging method for measuring far-field laser power density distribution is intro?duced. The diffuse-reflective board is used to collect laser power distribution information to a Mid-IR thermal imag?er. And a power detector is installed on the feature position of the board to fuse spot image grey information and ac?tual power value measured by a laser power probe. And the mapping relationship between grey value and power den?sity is obtained to estimate laser far-filed power density distribution. The system has low measurement error and it is simple, reliable and suitable for Mid-IR laser far field power density distribution measurement under different condi?tions, which can meet the present measurement requirements of high-power IR laser jamming equipments.
