時域熱反射測量系統(tǒng) (TDTR 測試系統(tǒng)）飛秒激光時域熱反射測量技術，即Time-domain Thermoreflectance, TDTR 是一種基于飛秒超快激光抽運探測（pump-probe）技術的導熱測量技術。相比于其他導熱測量技術，目前TDTR技術因其可以測量納米薄膜熱導率和界面熱阻以及非接觸式測量特性而具有*優(yōu)勢。

我司新推出的時域熱反射測量系統(tǒng)可用于測量金屬薄膜、塊體或液體的熱導率、界面熱阻等多項熱物性參數(shù)，薄膜測量厚度可達納米量級！在微納結(jié)構(gòu)新材料的研發(fā)與分析等方面得以越來越廣泛的應用。   

系統(tǒng)通過利用飛秒激光照射樣品表層金屬薄膜，令薄膜吸收能量并將其轉(zhuǎn)化為熱能， 從而傳導給樣品，并隨時間尺度逐漸向樣品傳遞。金屬薄膜表面溫度隨時間回落，從而影響到其反射率。屆時再通過測量另一束探測激光的反射強度曲線，通過后續(xù)一系列的解調(diào)分析，即可得到金屬薄膜溫度隨時間的變化，進而獲得被測樣品的導熱特性和相關熱物性參數(shù)等。
