摘要
对紫外告警系统成像子系统的信噪比进行了研究与分析,应用一种新的根据ICCD紫外成像系统采集的图像进行计算信噪比的方法,该方法解决了常用信噪比测试方法中待测参数多,采用测试仪器多,带来的误差较大等问题。根据该方法所搭建的实验系统不仅实现了数据的快速处理,还使观察者能够直观地看到被测目标的动态图像,同时也可以利用该方法系统地分析紫外告警成像子系统的不同情况下的噪声的特性。
By research and analyse of testing SNR method of imaging subsystem of UV warning system,a imaging precessing testing SNR method was adopted.The method used ICCD to calculate SNR with computer image processing technology and solves the questions of more pending parameters in the common method and more adopted meters bringing great error.High speed processing data was completed in the experiment system with the testing method.The image can be seen and measured.The method can be used to analyze the other noise parameters of UV warning imaging subsystem in detail.
