用Pt薄膜表面温度计测定激光加热的表面温度变化

APPLICATION OF Pt THIN FILM DETECTORS TO THE MEASUREMENT OF SURFACE TEMPERATURE CHANGES INDUCED BY LASER

用溅射Ｐｔ薄膜成功地探测了低功率Ｈｅ－Ｎｅ激光加热样品的表面温度变化，结合锁相技术，该系统能分辨的最小温度变化为１０－５℃．

By using sputtered Pt thin films,small changes of surface temperature induced by He-Ne laser are successfully recorded.Using the lock-in tecknique,the smallest temperature variation,which can be measured in this system,is 10-5℃.
