一种辐射测温的简便线性化方法

A NEW SIMPLE LINEARIZATION METHOD FOR RADIATION THERMOMETERS

本文提出辐射测温的一种简单线性化公式。该方法将信号电压直接作对数运算,便于数字式温度显示或其它线性仪表指示。计算机模拟表明,在常用的红外测温波段和温度量程范围内可获得较好的精度,适合于模拟电路结构的辐射温度计使用。

A new characteristie equation for radiation thermometers has been put forward in this paper. We used a logarithmic computing cireuit for the linearization of photo-electrical signal. The computer simulation and practical measurement show that, the simple method has a rather good relative accuraey for usual infrared thermometers.
