摘要
为实现液体变焦透镜的自适用调节功能,开发了一种基于单片机的液体透镜成像清晰度调节系统。系统选择PIC16F1847单片机作为主控芯片,高压DC-AC转换器MAX14521E芯片用于控制液体透镜实现变焦,达到可调节成像清晰度的目的。设计了一款用于成像清晰度调节的人机交互软件,软件功能包括液体透镜成像清晰度手动调节和自动调节,用户可根据使用需求在界面上选择调节模式。测试结果表明:该系统能够实现成像清晰度调节功能,性能稳定,自动调节速度快,电压驱动电路最高可输出120 V交流电压。
To realize the adaptive adjustment function of liquid zoom lens,a liquid lens imaging clarity adjustment system based on PIC microcontroller was developed.The system selected the PIC16F1847 microcontroller as the main control chip with the high-voltage DC-AC converter MAX14521E chip used to control the liquid lens to zoom to adjust the imaging clarity.A human-computer interaction software including the manual operation mode and automatically operation mode was designed to adjust the lens imaging clarity.The test results show that the system can realize the adjusting imaging clarity function,with stable performance and fast automatic adjustment,and the output AC voltage of the driving circuit reaches up to 120 V.
