Optical Wavefront Shaping in Biomedical Photoacoustics

Optical wavefront shaping is an emerging technique that controls light transportation in disordered media. It has attracted significant interest in the photoacoustics community in recent years. On one hand, photoacoustic signals can provide feedback on local light intensity to guide optical wavefront shaping non-invasively for focusing light through optically diffusive media. On the other hand, the wavefront shaping technique can be used to focus light through multimode fibres to achieve ultrathin photoacoustic endomicroscopy probes. This chapter reviews the latest research that lies at the intersection of wavefront shaping and photoacoustics, encompassing photoacoustic-guided wavefront shaping and multimode fibre-based photoacoustic endomicroscopy techniques.
