抄録

This paper describes improved models derived from an experiment in generation and propagation of photoacoustic signals in a drilled hole of an epoxy resin with different backing materials, a white polypropylene and a black one. The major difference between the improved and the old models is as follows. The photoacoustic signal at the top edge of the hole was generated not only due to absorbed incident light, but also due to absorbed and scattered light at the top edge of the hole. In addition, we show the propagation paths of the PA signals generated at the top edge of the hole.
