本文分析了利用AGA780型红外热象仪测试物体表面稳态温度场的基本原理和方法。作为实例,利用红外热象仪测试了一种航天仪表——PIGA浮子组件表面的稳态温度分布。最后,对红外热象仪测温的精度作了估计。
This paper analyzes the use of AGA780 infrared thermal imager to test the steady surface temperature field of the basic principles and methods. As an example, an infrared thermometer was used to test the steady-state temperature distribution on the surface of PIGA float assembly. Finally, the accuracy of temperature measurement by infrared thermal imager is estimated.
