一种精密结构无损检测技术俄罗斯ＣＴＯＫ研究所开发出一种激光热波显微无损检测系统．该系统利用钢蒸气激光照射被测工件表面，通过接收并测量其反射的红外波、探测激光脉冲加热在固体内部产生的热传导以及声振这３种信息来评价试件内部存在的缺陷．对３个通道拾取的信息... A sophisticated structure of non-destructive testing technology CTOK Institute of Russia developed a laser thermal wave microscopic non-destructive testing system. The system uses steel vapor laser to irradiate the surface of the workpiece under test and evaluates the defects existing inside the specimen by receiving and measuring the reflected infrared waves and detecting the heat conduction and acoustic vibration generated inside the solid by laser pulse heating.
