Abstract

The use of photothermal microscopy to obtain superficial and in-depth images, by means of the interaction of a thermal wave with the analyzed material, has reached great interest due to its numerous applications. The application of the photopyroelectric microscopy technique with pyroelectric ceramic as a detector to avoid deformations due to the sample weight is presented in this article. Pyroelectric ceramic and linear micro-positioners were used to obtain the local photothermal signal of the sample. Then it is possible to get images of the studied sample through their differences in local thermal and optical properties.
