摘要

Abstract: Precise radiometric and geometric transmission of images from CCD sensor to memory is a fundamental aspect of CCD camera calibration. Line jitter and other degradations occurring during transmission are major limiting factors of the precision attainable with most current CCD cameras and framegrabbers. The influence on line jitter by framegrabbers with PLL (phase locked loop) and principal electronic components involved in synchronization and transmission are analyzed and discussed. The method and the algorithm for detection of the line jitter are discussed through the experiments detailed in this report. The experimental results of the detection of line jitter are taken as an important quality index for CCD evaluation. !4
