A MEASURING HEAT-VISUALIZATION TECHNIQUE USING THERMOCHROMIC LIQUID CRYSTALS
【摘要】 简要介绍了热色液晶定量测热显示技术的特点和实施方法。给出了在等熵压缩管炮风洞中进行的测热实验的初步分析结果。
【Abstract】 This article simply introduces the characteristics and methods of a measuring heat-visualization technique using thermochromic liquid crystals. It includes measuring principle,acquisition and quantification of colour light signals,and accuracy of measurements. Finally, the initial test results done at an isentropic light piston tunnel (ILPT) hypersonic facility are provided.
