| 中文摘要 | 采用室温光导型HgCdTe探测器,研制了可用于中红外激光功率密度测量的探测单元,主要包括衰减片、探测器、放大电路、数据采集和信号处理5个部分。分析了室温中红外HgCdTe光电探测器的温度特性,并提出了探测器响应率温度自适应校正模型。该探测单元工作温度为-40~30℃,功率密度测量不确定度小于20%。; A detecting module for measuring power density of mid-infrared laser is developed using room temperature HgCdTe photoconductor detector.The module is consisted of optic filter attenuator,HgCdTe detector,amplifier,analog to digital converter,and signal processor.The temperature characters of the HgCdTe detector are analysed,and the responsivity self-adjusting model of detector with temperature is established.The module is suitable for power density measuring of mid-infrared laser when the working temperature is-30~40 ℃,with measurement uncertainty less than 20%. |
