Spectral properties of the forward operator in photo-acoustic tomography

Research output: Contribution to conferenceConference abstract for conferenceResearchpeer-review


Photo-acoustic tomography (PAT) exploits an interaction between electromagnetic and acoustic phenomena. Accordingly, a standard forward model underlying PAT involves an elliptic PDE with internal data coupled with a hyperbolic initial-boundary problem. For both component problems one can formulate a forward operator that maps a feature of the sample (light absorption, diffusivity) to internal or boundary data. We investigate spectral properties of the composition of the two forward operators, exploring the interplay between the component operators.
