摘要
探讨了辐射温度计内调焦系统象方孔径角的变化规律,并以WDH-Ⅲ型小目标光电温度计为例,介绍了该光学系统的应用结果:温度在测量距离从0.5m变化到2.0m的情况下,仪表示值误差为测量值的0.1%。
The varying pattern of the aperture angle on image side of the focusing system in radiation thermometer is investigatcd. With the WDH- III type opto-electronic thermometer for small objects as an example, the application result of 0.1% indication error within 0.5m to 2.Om mea-suring distance is introduced.
