摘要

针对单路激光扫描光绘机在12000 DPI精度工作效率低下的缺陷

提出基于FPGA+DDS实现16路激光串行同步扫描的技术.该技术将高速FPGA器件与DDS芯片有机结合起来

原本扫描一个点时间215 ns

经过16路时分复用

在同样的时间内能够完成16个点的扫描.详细介绍了系统的工作原理、硬件设计和相应的软件实现

通过实验测量分析

该技术在高精度条件下

相对4路激光并行扫描光绘机

其工作效率提高了2

倍.

Abstract

The 16-channel laser serial synchronized scanning technology is provided based on the FPGA and DDS

to overcome the single-channel laser scanning raster plotter's low efficiency at 12000 DPI.The number of scanning spot can be increased from 1 to 16 in the same time of 215 ns by 16 TDM.The system's working principle and the corresponding hardware and software design are specified.The efficiency of this technology can be improved to 2

times than that of the 4-channel parallel laser scanning raster plotter and validated by experimental analysis at high DPI.
