Flat-correction Method for Fiber Optic Taper Coupled CCD Camera
光纤耦合CCD相机的平场校正方法研究

The Photo-Response Non-Uniformity(PRNU) in the fiber optic taper coupled CCD camera is discussed. The flat-correction method especially for the system mentioned above is a very useful method to get a better image. The method is deduced in detail by analyzing the components in the signal output with the CCD camera. Some images with very big PRNU problem are processed by the flat-correction method and the good result can be obtained. The flat-correction of image output by the fiber optic taper coupled CCD camera is necessary. One example is given to show the effect of the flat-correction method.
