footage speed

This paper presents a method of improving on frame & horizontal synchronization in laser phototypesetter , by using singal - chip computer system to detect real - time frequency deviation and adjust film transmission speed
摘要提出了一种在激光照排机电控系统中，利用单晶片微机对转镜扫描光栅频率信号的暂态波动量进行检测、提取，并以此实时校正系统输片速度，实现场扫描对行扫描的跟踪、补偿，从而提高行、场扫描同步精度的方案。
