Remote sensing applications of pulsed photothermal radiometry
Abstract
The technique of pulsed photothermal radiometry (i.e., detection of the transient infrared thermal radiation from a condensed matter sample heated by a short-pulsed radiation is useful for signal-ended remote sensing applications. Applications for spectroscopic detection, measurement of absolute absorption coefficients in opaque materials, and sensing of dimensions or thermal properties in inhomogenous material are demonstrated. Theory of PPTR technique in the simple case of a semi-infinite homogenous material is described.
