摘要:
Three‐dimensional thermal diffusion effects are shown to be important for photothermal imaging. Signal enhancement near thermal boundaries is observed. The effects are applied to locating defects in a crystalline ceramic. A general application to signal enhancement in powders over bulk solids is suggested.
