    摘要:

    介绍了以高信噪比同时测量近室温目标温度和光谱发射率的中红外多波长辐射温度计,详细说明了其光学系统及电气系统设计.采用高像质、大光通量的折反式光学系统和闪耀光栅分光系统,通过多元碲镉汞探测器线列及电气系统,可同时检测目标温度及发射率.内置黑体炉和热管恒温视场光栏和孔径光栏减小了周围环境温度漂移及杂散光对温度测量的影响.

    Abstract:

    A brand-new kind of mid-infrared multi-waveleng th radiation thermometer for the measurement of true temperature and emissivity near room temperature with high signal-to-noise ratio (SNR) was presented. By ap plying blazed grating and refractive-reflected optical system with high image q u ality and throughput, the temperature and emissivity were available simultaneous ly by the MCT semiconductor sensor array and electric system. Inner blackbody so urce was installed to compensate the surrounding temperature drift, and the temp erature of field stop and aperture stop was controlled by a heat pipe to reduce th e influence of stray radiation on temperature measurement. The main structures o f optical and electric systems were described in detail.
