Photo-acoustic tomography is an imaging method that attempts to combine the high resolution of ultrasound and the high contrast capabilities of electromagnetic waves. In this talk we will first introduce the mathematical problems photo-acoustic tomography presents. Uniqueness results will briefly be discussed for the situation when sound speed is known and the source term is to be recovered. Then the case when both sound speed and source term are unknown will be considered. Partial uniqueness results in this case proved by Liu and Uhlmann will be presented along with an outline of the proof which relies on the temporal Fourier transform.
