This document summarizes a presentation on photoacoustic imaging with coherent light. It discusses how photoacoustics can be used to image in optically scattering media by coupling light and ultrasound. Two approaches for photoacoustic image formation are described: reconstruction-free imaging using time-resolved signals and reconstruction-based tomography. Enhanced imaging techniques using speckle illumination and wavefront shaping are presented, including a photoacoustic transmission matrix approach that allows focusing light through scattering samples. Challenges and potential solutions for deep tissue imaging are also outlined.
