摘要
传统的可溯源热电偶动态校准系统采用CO2 激光器作为光源,存在着光路调节不便、激光光斑能量分布不均匀的特点,无法保证传感器均匀加热。半导体激光器的光源具有输出光斑能量稳定、均匀、发散角较大的特点。利用Zemax 软件对光路进行优化设计,选取合适的光纤和透镜进行耦合,精简了可溯源热电偶动态校准的光路设计,使激光光路调控更加方便,保证了热电偶的均匀加热。实验结果表明:这种设计大大降低了光路调节难度,提高了激光的利用率,为热电偶的动态校准提供高质量的激光光源。
Abstract
The traditional traceable thermocouple dynamic calibration system uses CO2 laser as the light source, which has the characteristics that laser light energy distribution is not uniform , the adjustment of optical path is inconvenient and heated uniform of the sensors cannot be guaranteed. The light source of semiconductor laser had stable and uniform output light spot, but the divergence angle is large. In order to simplify traceable thermocouple dynamic calibration optical design, control the laser light path more convenient, and ensure the uniform heating of the thermocouples, the appropriate fiber optic and lens coupling are selected using Zemax software to improve the light path. The results show that the design greatly reduces the difficulty of light path adjustment, improves the efficiency of the laser, and provides high quality laser source for the traditional traceable thermocouple dynamic calibration system.
