针对目前常用的单通道和多通道激光器测量方法的机理和无法解决的实时测量问题，提出了利用激光器阵列方法测量烟幕对红外辐射的干扰效能的思想。利用红外激光器均匀化整形等技术实现了对烟幕干扰红外成像时红外透过率的实时测量，解决了由于烟幕在红外成像视场中不断变化所带来的透过率测量随机性问题。通过计算典型试验条件下各方法的测量结果，给出了测量精度改进的定量分析。

In terms of the mechanism of common single-channel and multi-channel laser measurement methods and the existing difficult real time measurement problem, an idea to use a laser array to measure the jamming efficiency of smoke againstinfrared radiation is proposed. By using the homogenized shaping technology for infrared laser beams, the real time measurement of the infrared transmittance of infrared imaging is implemented when smoke jamming is used. The random problem in transmittance measurement caused by the changing of smoke in an infrared imaging field of view is solved. By calculating the measurement results of different methods under a typical test condition, the quantitative analysis is made for the improvement of measurementaccuracy.
