时域热反射测量系统 (TDTR 测试系统）飞秒激光时域热反射测量技术，即Time-domain Thermoreflectance, TDTR 是一种基于飞秒超快激光抽运探测（pump-probe）技术的导热测量技术。相比于其他导热测量技术，目前TDTR技术因其可以测量纳米薄膜热导率和界面热阻以及非接触式测量特性而具有*优势。
我司新推出的时域热反射测量系统可用于测量金属薄膜、块体或液体的热导率、界面热阻等多项热物性参数，薄膜测量厚度可达纳米量级！在微纳结构新材料的研发与分析等方面得以越来越广泛的应用。
系统通过利用飞秒激光照射样品表层金属薄膜，令薄膜吸收能量并将其转化为热能， 从而传导给样品，并随时间尺度逐渐向样品传递。金属薄膜表面温度随时间回落，从而影响到其反射率。届时再通过测量另一束探测激光的反射强度曲线，通过后续一系列的解调分析，即可得到金属薄膜温度随时间的变化，进而获得被测样品的导热特性和相关热物性参数等。
