| 摘 要： | 为了研究激光半主动制导中1.06μm和10.6μm两种红外激光的能量分布和其它参数,提出了一种通过摄取灰度图像进行测量的新方法。讨论了激光对靶面温度分布的影响、摄像机对回波信号的接收特性,并建立了测量过程中光-电-图像信号转换的数学模型。针对某型10.6μm激光指示器,依据模型对输出进行了仿真,得到了仿真灰度分布与真实灰度分布相似程度较好、其二维相关系数为0.88995的结果。结果表明,模型是正确的,可以采用此方法对这两种激光进行测试。

| Abstract: | In order to study the energy distribution and other parameters of 1.06μm and 10.6μm lasers in the laser semiactive guidance,a new measurement was put forward based on gray photograph. The influence of laser on the target temperature distribution and the receiving property of infrared video camera was discussed in detail. A mathematical model from optical signal to electric signal to image signal is built up . For a certain 10.6μm laser guided-instrument,its output was simulated according to the model. The obtained result was similar to the actual outcome and the 2-demension correlative coefficient was 0.88995.Theresult shows that the model is correct and it can be used to test the 1.06μm and 10.6μm lasers. |
