光纤F-P滤波器驱动电压自动调整电路设计

本项目设计光纤F-P滤波器驱动电压自动调整电路,利用PC机检测光纤F-P滤波器的漂移情况,微处理器与PC进行数据通信获得漂移情况后控制D/A转换器产生直流偏置电压,与三角波电压叠加后对驱动电压进行自动调整,从而消除温度对光纤F-P滤波器的影响。

This project aims at designing an optical fiber F-P filter driven automatic voltage regulation circuit through using fiber F-P filter PC machine to detect drift. The micro-process or data communication with the PC gain drift after control D/A converter generates a DC bias voltage, and the triangular wave voltage superimposition and automatically adjusts the driving voltage, thereby eliminating the influence of temperature on the optical fiber F-P filter.
