時(shí)域熱反射測量系統 (TDTR 測試系統）飛秒激光時(shí)域熱反射測量技術(shù)，即Time-domain Thermoreflectance, TDTR 是一種基于飛秒超快激光抽運探測（pump-probe）技術(shù)的導熱測量技術(shù)。相比于其他導熱測量技術(shù)，目前TDTR技術(shù)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(shí)域熱反射測量系統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，薄膜測量厚度可達納米量級！在微納結構新材料的研發(fā)與分析等方面得以越來(lái)越廣泛的應用。
系統通過(guò)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化為熱能， 從而傳導給樣品，并隨時(shí)間尺度逐漸向樣品傳遞。金屬薄膜表面溫度隨時(shí)間回落，從而影響到其反射率。屆時(shí)再通過(guò)測量另一束探測激光的反射強度曲線(xiàn)，通過(guò)后續一系列的解調分析，即可得到金屬薄膜溫度隨時(shí)間的變化，進(jìn)而獲得被測樣品的導熱特性和相關(guān)熱物性參數等。
