時域熱反射測量係統 (TDTR 測試係統）

飛秒激光時域熱反射測量技術，即Time-domain Thermoreflectance, TDTR 是一種基於(yu) 飛秒超快激光抽運探測（pump-probe）技術的導熱測量技術。相比於(yu) 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麵熱阻以及非接觸式測量特性而具有獨特優(you) 勢。

我司新推出的時域熱反射測量係統可用於(yu) 測量金屬薄膜、塊體(ti) 或液體(ti) 的熱導率、界麵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與(yu) 分析等方麵得以越來越廣泛的国产成人在线观看免费网站。   

時域熱反射測量係統 (TDTR 測試係統）通過利用飛秒激光照射樣品表層金屬薄膜，令薄膜吸收能量並將其轉化為(wei) 熱能， 從(cong) 而傳(chuan) 導給樣品，並隨時間尺度逐漸向樣品傳(chuan) 遞。金屬薄膜表麵溫度隨時間回落，從(cong) 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，通過後續一係列的解調分析，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(guan) 熱物性參數等。
