Smear correction of high frame rate camera based on asynchronous CCD drive

The vertical smear correction of a high frame rate camera has been carried out, which takes a series of images and CCD vertical binning into consideration. Compared with the traditional arithmetic for static images, such as reversely stepwise correcting method, the arithmetic presented in this paper is fit for continuous images, particularly for the images acquired with binning. The method has been applied to a newly developed high frame rate camera based on asynchronous CCD drive which is capable of operating up to 40 000 frames per second, and the processed images proved the effectivity of this method.
