摘　　要：介绍激光光热辐射技术检测材料缺陷的原理和实验技术 ,设计的硬件与软件实现了测量自动化 。The principle and experimental method for detecting material defects by laser technique were introduced. Automatic inspection was realized by the circuit and software designed. The position and size of a defect in composite sample could be determined by the amplitude and phase of photothermal signals.
