| Abstract: | In the computer testing of distortion of micro-CRTs , it is necessary to solve the problem that the resolution of the system usually can not meet the requirements of the preci- sion. In this paper , the properties of distorted scanning line are carefully analyzed , noise intro- duced by the image collecting system is discussed in detail , and ways to suppress the noise is proposed, so that the limits which were placed on acquiring of high-precise parameter of distor- tion can be broken through now. |
