The most important is to optimize the design of light path and electronic circuit of the system so as to maximize the snr through noise inhibition 其重点是优化系统光路和电路的设计、最大限度的抑制噪声,提高检测系统的信噪比。
At last , discussed the light path and the circuit of the measurement system , especially the amplifier circuit . after the experiments , partial result has been listed in this paper 最后,文章进行了测量系统的设计,对测量系统的光路部分、电路部分中的微信号放大电路进行了设计。
The basic components and operation principle of infrared moisture meter , designing and assembling the light path and hardware circuit of the system are introduced in detail , the program is compiled and debugged 对系统的光路和硬件电路进行了详细的设计与装配,编写了系统软件程序,并进行调试。
Secondly , the adjustment device for light path of the measure system is designed and key structure dimension and assemble errors is studied . accordingly , the system mechanical structure is confirmed 其次,设计了测量系统的光路调节装置,并进行了主要结构尺寸和装配误差的分析,进而确定了系统的机械结构。
It adapts to be used in the foul and hazardous environment . the hardware of this apparatus is designed , such as light path design , gas chamber fabricating and light source drive 文中详细讨论了光纤传感二氧化硫气体浓度检测仪的硬件设计,进行了光路、气室的设计,并详细分析和讨论了光源的驱动及其稳定性、光源的调制、谐波信号的拾取和处理等问题。
