摘要
本文介绍了一种交/直流两用光功率计的设计与实现方法。通过该光功率计可以方便、快速地对交流或直流光进行功率测量。另外,通过对电路及电源等的优化处理,极大地扩展了整机的动态范围。
The design and realization of AC/DC Optical Power Meter,which can measure the power of the AC light or DC light conveniently and rapidly, are introduced in this paper. In addition, by optimizing the circuit and power,the dynamic range of the instrument is extended greatly.
