本文提出了视频信噪比转移函数概念,建立了摄像CCD微光图像灵敏(?)方程.实验证实了理论模型的合理性.根据这个方程用计算机模拟计算了几种条件下微光CCD摄像器件探测曲线.分析这个结果后提出了提高CCD微光图像探测能力的几种途径.
In this paper, the concept of the transfer function of video signal-to-noise ratio is proposed, and the sensitivity (?) Equation of the CCD image is established. The rationality of the theoretical model is verified by experiments. According to this equation, Detection curve.After analyzing this result, several ways to improve the detection ability of CCD glimmer image are proposed.
