Selecting Distributed Feedback Laser Diode as light resource and the gas absorbing cell with fiber pigtail as its sensor, and using lock in amplifier to distill signal and harmonic measure technology to process that distilled faint signals, we design an instrument of remote and on-line measuring acetylene.

选用分布反馈式半导体激光器作为激发光源，带尾纤的气体吸收气室作为传感器的探测头，以及锁相放大器来提取信号，并通过谐波检测技术对所提取的微弱信号进行处理，设计了一套远距离在线测量乙炔气体的监测仪器。

So when the wavelength of the incident light changes, only the position of rhomb-type retarder need to be changed to allow the light to represent oblique incidence in the front of rhomb, and then selecting suitable incident angle can compensate the dispersion phase deviation, and make the same rhomb possess standard λ/4 phase retarder under all different wavelengths.

当入射光的波长改变时，只需改变菱体延迟器的方位，让光线在菱体的前端面上斜入射，适当选取入射角，就可以补偿相位延迟的色散偏差，使同一菱体达到对不同波长都满足λ/4相位延迟。

The stable and reliable operation voltage of the probe can be given by the following methods:(1) 20% light coupling efficiency is obtained by direct coupling of LD-optical fiber.(2) The light power is transmitted by multi-model optical fiber.(3) The largest photo-electric conversion efficiency is achieved by selecting the transformer regulation of step-up transformer.(4) The stable light intensity is achieved by using LD light feedback of driving circuit and refrigeration.

通过下述方法可提供稳定、可靠的探头工作电压：LD—光纤的直接耦合方式，可实现20％左右的光耦合效率；采用多模光纤传输功率；选择升压变压器最佳变比提高光电转换效率；采取LD驱动电路光反馈以及致冷措施使其发光幅值稳定。
