Abstract

A high resolution laser scanning image system (HRLSIS) is introduced in this paper. A 7 element f(theta) lens is designed, which linear distortion is less than 0.04% and MTF of all fields more than 0.5. Using a optical compensation method, pyramidal error of the rotating prism is less than 1'. Performance achieved by the HRLSIS is: length of scanning line is 200, pixel count per line is 8000, position accuracy of adjacent pixels is less than 5 (mu) .
