摘要
研究了一种基于廉价传感器OPT201、数字处理电路和嵌入式系统的激光脉冲峰值功率实时检测系统,介绍了该系统的设计思路。提出利用传感器与被测峰值功率之间的关系以补偿采样检测数据的方法。通过对该方法的实验观测,可实现在重复频率为4kHz以下的峰值功率高精度检测,检测误差整体小于1%。
The real-time detection system of pulsed laser peak power based on low-cost sensor OPT201, digital control circuit and embedded system is proposed in this paper, and how to design the system is also emphatically introduced. A new method that utilizing the relationship of sensor and measurement to compensate for sampled date is introduced in this design. The results of experiments show that detection error is less than 1%, at frequencies below 4 kHz.
