Abstract

The potential of photothermal radiometry for subsurface defect imaging in shells of Crassostrea virginica is explored. It is shown that using this technique in the modality of modulated frequency, it is possible to obtain photothermal images in the case of small thermal diffusion lengths. By controlling the modulation frequency, it is shown that the technique can be useful in the study of buried defects in the shell. The application of this technique in monitoring living organisms is discussed.
