Abstract

Thermal-wave field diffraction has been treated as the extreme near-field approximation of a three-dimensional superposition integral that includes the generating optical aperture function. This formalism is quite general and is convenient for applications with many experimental diffracting apertures. Specific examples of useful photothermal excitation apertures have been treated explicitly. These include the spatial impulse function, a Gaussian laser beam, a circular aperture, and an expression for the interference field generated by two Gaussian laser beams.
