摘要： 热色液晶是一种能以不同颜色反映不同温度的液晶.热色液晶在其温度显示范围内呈现的每一种颜色,均对应着一个确定的温度.本文描述了热色液晶的主要结构,测温的原理,并介绍了采用扫描仪采集液晶温度变化图像,标定液晶色度与温度的一种方法,建立了扫描仪采集液晶图像系统,最后给出了该方法热色液晶色度与温度之间的经验关系式.

关键词: 热色液晶；温度；色度；标定；

Abstract: Thermochromic liquid crystal is one of the crystals that can reflect the temperatures by different colors.The special color shown by the thermochromic liquid crystal in its scope of the working temperature corresponds to a certain temperature.This paper describes the main structure of the thermochromic liquid crystal and the principle of the temperature measurement.It introduces the method of collecting the temperature images of the thermochromic liquid crystal and demarcating the hue of the thermochromic liquid crystal and the temperature.The correlation of the hue and the temperature is obtained.

Key words: thermochromic liquid crystal； temperature； hue； correlation；
