Abstract
This paper describes a high-fidelity tomographic imaging reconstruction method for photopyroelectric thermal wave detection equipment. The high-fidelity is achieved through a high signal-to-noise ratio detection technique and through a new calculation algorithm. A very-smalldiameter detection metal probe tip can be used due to the high signal-to-noise ratio detection technique, increasing the spatial resolution. The calculation algorithm which considers thermal wave transmission paths along with defects achieves the high-fidelity tomographic imaging reconstruction.
