時域熱反射測量系統 (TDTR 測試系統）飛秒激(ji)光時(shi)域熱(re)反射測量(liang)技(ji)(ji)術，即(ji)Time-domain Thermoreflectance, TDTR 是(shi)一(yi)種基于飛秒超快激(ji)光抽(chou)運探測（pump-probe）技(ji)(ji)術的導熱(re)測量(liang)技(ji)(ji)術。相比于其他導熱(re)測量(liang)技(ji)(ji)術，目前TDTR技(ji)(ji)術因其可以(yi)測量(liang)納米薄(bo)膜熱(re)導率和界(jie)面熱(re)阻以(yi)及非接觸式測量(liang)特(te)性(xing)而具(ju)有(you)*優勢。

我司新推出的時域熱(re)反射測(ce)(ce)量(liang)系統可用(yong)于測(ce)(ce)量(liang)金屬薄膜(mo)、塊體或液(ye)體的熱(re)導(dao)率(lv)、界(jie)面熱(re)阻等多項熱(re)物(wu)性(xing)參數(shu)，薄膜(mo)測(ce)(ce)量(liang)厚度(du)可達納米量(liang)級！在微納結(jie)構新材料的研發與分析等方面得以越來越廣泛的應用(yong)。   

系統通(tong)過(guo)利用飛秒激光照(zhao)射(she)樣品(pin)表層金(jin)(jin)屬(shu)薄(bo)膜，令薄(bo)膜吸收能量并(bing)將其(qi)轉化為熱(re)(re)能， 從而(er)傳(chuan)導給樣品(pin)，并(bing)隨時間(jian)(jian)尺度逐(zhu)漸向樣品(pin)傳(chuan)遞。金(jin)(jin)屬(shu)薄(bo)膜表面溫度隨時間(jian)(jian)回落，從而(er)影響到其(qi)反射(she)率。屆時再通(tong)過(guo)測量另一束探測激光的(de)(de)(de)反射(she)強度曲線(xian)，通(tong)過(guo)后續(xu)一系列(lie)的(de)(de)(de)解調分析，即可得(de)到金(jin)(jin)屬(shu)薄(bo)膜溫度隨時間(jian)(jian)的(de)(de)(de)變化，進而(er)獲得(de)被測樣品(pin)的(de)(de)(de)導熱(re)(re)特性和(he)相關(guan)熱(re)(re)物性參數等。
