以国产石英光纤作光路、硫化铅探测器为敏感元件所构成的中温光纤辐射测温仪，在２００℃以上实现了１℃分辨力的温度检测；以氟化物光纤作光路、硒化铅探测器为敏感元件，初步实验结果是８０℃以上获得了１℃的分辨力。提出一种新的桥路双平衡调解法，较好地解决了半导体探测器的温漂问题。系统所采用的积分与累加检测法对噪声与干扰有明显的抑制作用。
The domestic optical fiber made of quartz optical fiber, lead sulfide detector for the sensitive components of the temperature optical fiber thermometer, at 200 ℃ above the temperature of 1 ℃ to achieve a resolution; fluoride fiber optical path, lead selenide detector As a sensitive element, the preliminary experimental result is that the resolution of 1 ° C is obtained above 80 ° C. Proposed a new bridge double balance mediation method to better solve the temperature drift of semiconductor detectors. Integral and cumulative detection methods used by the system have significant inhibitory effects on noise and interference.
