本文叙述了热塑录象的工作原理,给出了用光导摄象转换和布阵声全息系统视频信号直接馈送两种方式记录声全息图和光学重建的结果。证实热塑录象可用于布阵声全息图的实时重建。本文还讨论了热塑录象在无损检测中的应用前景。
This paper describes the working principle of thermography and gives the results of recording holograms and optical reconstruction in two ways by using photoconductive image conversion and arrayed acoustic holography system. Confirmed that the thermoplastic video can be used for the real-time reconstruction of the array acoustic hologram. The article also discusses the application of thermography in nondestructive testing.
