摘要
针对光栅光调制器阵列的显示控制,提出了一种控制系统设计方案。设计应用软件,产生显示数据源,由USB数据线发送到FPGA芯片,在FPGA芯片上实现格式转换、乒乓操作、脉宽调制等模块电路。实验结果表明,该控制系统操作灵活方便,为测试光栅光调制器的显示参数提供了有力的技术支持。
A design of control system was proposed to control the display of grating light modulator array. Display data source is produced by application software and the data is transmitted to the FPGA chip by USB data line. Module circuit like format conversion,pulse width modulation and ping-pong operation were implemented on the FPGA chip. The result indicated that the control system is flexible and convenient to operate. It provides the powerful technical support for testing display parameters of grating light modulator.
