激光印字过程的数学描述及畸变分析

Mathematical Representation and Distortion Analysis for Laser Printing

本文应用过程算符■和子过程算符■,描述了自行研制的激光印字机印字过程,指出了印字过程中文字信息的畸变函数,并以激光扫描系统为例阐述了该系统中文字信息产生的畸变,提出了消除畸变的途径,并给出了扫描位移曲线和校正前后的印刷实样。

The printing process by a laser beam printer is described with process operator G and subprocess operator gi. A distortion function for Chinese character information is proposed, With a laser beam scanning system as an example, the distortion of characters information in the system is described and the way of eliminating the distortion suggested. The scanning displacement curve and press proof before and after revision are shown.
