Terahertz imaging non-destructive inspection system and method

摘要: Provided are a system and method using terahertz imaging techniques for performing non- destructive inspection of structure detection surface recesses. A may involve applying terahertz-frequency absorbing liquid to the structure, whereby will naturally tend flow into recesses present in removing excess from which has not penetrated existing and, after been removed transmitting electromagnetic radiation frequency range toward detecting reflections is absorbed at structure. use applicator, remover, transmitter, receiver perform non-destructive operation.
