摘要
本文介绍JGY-1型红外激光光声光谱仪信号检测,对如何减小噪声、干扰、提高检测灵敏度,保证良好的线性等问题进行了较为详细的讨论。给出了有关器件的特性及实验测试方法;讨论了防止地电流干扰的具体方法。
This paper describes the weak signal detection of JGY-IR laser optoacoustic spectrometer The problems relating to reduce noise and interference, increase sensitivity and obtain good linearity are discussed in detail. The characteristics of the apparatus concerned and the method of experiment are given. The practical measures for preventing interference of ground-loop currents are introduced. Finally, an example of optoacoustic spectrum is given.
