| 4. | This paper first analyzes the key techniques of the semi - conductor technology according to the physical features of the thermoelectric cooler ( tec ) , and then provides the overall blue - print design of this system
本文首先根据半导体制冷器( tec )的物理特性分析了半导体制冷技术的关键,给出了系统的总体设计方案。 |
| 5. | This system can be used to test the optical output power of sld automatically . firstly , the principle and characteristic of sld have been analyzed . the effect of sld ' s stability on ifog and the theory of thermoelectric cooler ( tec ) have also been discussed in this paper
首先，本文分析了sld光源的原理和特性，并且介绍了驱动电流的波动和温度的变化对sld光源的影响，分析了光源的稳定性对光纤陀螺性能的影响和光源内部控温器件半导体制冷器的工作原理。 |
| 6. | The temperature of the f - p cavity is accurately controlled by a set of thermoelectric cooler ( tec ) modules attached on the body of the cavity and the electronic feed - back circuit . we found that the long - term unidirectional frequency shift of the output laser resulting from the slow increase of the cavity length under the effect of the temperature integration on the cavity body is essentially eliminated
因此，往往有多台f ? p腔出现在同一个实验装置中本文利用珀耳帖元件，对稳频系统中作为频率参考标准的fabry ? perot干涉仪进行精密控温，并利用f - p腔的透射特性，对自制的全固化单频nd ： yvo _ 4激光器稳频。 |
