Abstract

In this work, Fourier transform based analytical solution to photoacoustic wave equation is obtained for an optically absorbing spherical object warmed up by a pulsed laser for rectangular and Gaussian radial profiles by treating the temporal profile of the laser as Gaussian. The photoacoustic signal is investigated as a function of time for different locations outside the spherical object. An expression including the dependency of the laser parameters on the photoacoustic signal is presented.
