摘要
为了改善激光共聚焦显微镜振镜控制板卡控制方式复杂、信号响应时间较长、匹配易出错及成本较高问题,设计一款基于FPGA的振镜扫描控制系统。系统使用FPGA作为振镜扫描控制系统的控制核心,与自主设计的硬件电路协同工作,通过FPGA直接给出振镜的工作时序控制振镜运动。观察时序仿真与振镜运动时测得的波形可知,振镜系统控制信号匹配正确、工作正常,测试Y振镜信号响应时间仅为4μs,在Y振镜信号完成时间的2%以下,满足设计要求。系统整体可调性较强,可以替代昂贵的控制板卡应用于激光共聚焦显微镜系统。
In order to improve the control mode of galvanometer control board of laser confocal microscope,which is complex,and has long signal response time,error prone matching and high cost,a galvanometer scanning control system based on FPGA is designed.In this system,FPGA is used as the control core of galvanometer scanning control system,which works together with the self-designed hardware circuit.Through FPGA,the working sequence of galvanometer is directly given to control the galvanometer movement.Through the time sequence simulation and the observation of the wave form measured when the galvanometer moves,the designed gal⁃vanometer control module signal matches correctly and works normally.The response time of Y galvanometer signal is only 4μs,which is less than 2%of the completion time of Y galvanometer signal,and can meet the design requirements.The system has strong adjust⁃ability and can be used in the laser confocal microscope system instead of expensive control board.
