Abstract
A specimen that is subjected to pulsating illumination may experience oscillating temperatures due to absorbed radiation. Depending on the spatial, spectral and temporal properties of the illuminating radiation, information on the chemical composition and the material qualities of the specimen may be obtained by observing pulsations in the thermal re-radiation from the sample. The basic principles of the technique are reviewed, and examples are presented on infrared and visible spectral studies of powders and biological material and on scanning/imaging applications. Distinguishing features of the technique are discussed, with a view to possible future developments.
