| 摘 要： | 在介绍一种利用InGaAs/I半导体激光器实现的实时测温系统的基础上,着重从硬、软两方面研究了在该系统中所采取的提高其温度测量精度的若干措施:一是精选探测器、优化设计调制盘并进行选频放大;二是在调制盘与探测器之间置一窄带滤光片;三是采用水冷遮蔽板并进行电气补偿;四是提高系统的采样精度。进行了一些必要的分析和讨论。

| Abstract: | A real time temperature measurement system with InGaAs/I is introduced at first.Then measures to improve the accuracy are discussed.The first is to select the detector,optimize modulation disk and amplify the signal with selective frequency.The second is to place a narrow band filter between modulation disk and the detector.The third is to use water cooling shelter and take electrical compensation.The fourth is to improve the sampling accuracy of the system.At last some relative analyses and discussion are put forward. |
