红外辐射光转换系统在温度测量中的应用

摘要

This paper analyzed the principle and method of infrared radiation conversion,developed an infrared radiation temperature measurement system for high-speed moving object temperature detection. Starting from the actual application, it discussed in detail about the hardware circuit design,the temperature calibration and temperature curve fitting. Hardware circuit design included photoelectric conversion,pre-amplification and temperature modules. It designed the temperature calibration experiments to obtain data. It chose the exponential model to fit the temperature curve after comparing several models,then presented the error a-nalysis. Finally,it showed the testing results of the whole system.%分析红外辐射光转换的原理及方法,研制红外辐射测温系统,用于高速运动物体的温度检测.从实际应用情况入手,对硬件电路设计、温度标定以及温度曲线拟合进行了详细论述.硬件电路设计主要包括光电转换、前置放大和恒温模块.设计温度标定实验获取数据.经多个模型比较,选用了指数模型,用来拟合电压温度曲线并进行了拟合误差分析.最后给出了整个系统的测试效果.
