摘　　要：针对红外测温仪测温准确性不高,易受环境、距离、辐射率等影响的问题,设计了一种新型的光学点温测温仪,该测温仪以光学和热学理论为基础,结合应用点像望远镜原理,利用自聚焦透镜替代二次透镜,通过光纤在像面接收光波并传输转换至电信号处理单元,真正实现了点温测量,最后,提出了系统软硬件设计的原理和方法。经过精确的标定和调试,其结果表明,该测温仪完全能满足非接触式工业温度测量要求。Aiming to solve the problem that measurement of the infrared instrument is not accuracy enough and is vulnerable to be affected by environment,distance,and radiation,a kind of new instrument of dot temperature measurement was designed,which was based on optical and thermal theory,using the principle of telescope.The general lens were instead by GRIN lens,then the optical fiber receives light waves in the image plane and the signal was transmitted to signal processing unit,really reaching the goal of dot temperature measurement.The principles and methods to design the software and hardware about the system were provided.The result indicates that the requirements of non-contact industrial temperature measurement are completely acquired through the precise calibration and commissioning.
