摘要
为了压抑相干噪声,本文采用白光光源编码技术,分别在凹球面反射镜系统和透镜系统中实现了部分相干光的图像微分。实验结果表明,输出图像有较高的信噪比,而且方法简便。
In order to suppress the coherent artifact noise,a technique of image differentiation utilizing white-light source encoding is descr- ibed and used in concave spherical mirror system and lens system individually.The experiment results show that output images have a higher signal-to-noise ratio,and the technique is simpler.
