摘要:

基于比色测温原理,论述了比色测温理论中的滤光片带宽,得出滤光片带宽对测温精度的影响很大,并不能简单的将峰值透过率波长代替整个带宽。然后通过考虑滤光片的带宽导出合理的比色测温算法,并通过实验证实此算法大大减小了测温误差。

关键词: 比色测温, 滤光片, 带宽, 算法

Abstract:

Based on the colorimetry of temperature measurement, the filter bandwidth of the colorimetry of temperature measurement is discussesd, and the filter bandwidth can greatly gaffect the measure precision is elicited, the peak transmittance wavelength can't be simply used to substitute for the whole bandwidth. Then the right algorithm is derived by analyzing the bandwidth, and the algorithm can decrease the measure error is verified by experiment.

Key words: colorimetry of temperature measurement, filter, bandwidth, algorithm
