Abstract: Optoacoustic (photoacoustic) tomography (OAT) is a hybrid imaging modality that enables high-resolution optical imaging at depths that exceed the optical diffusion limit by combining optical excitation with acoustic detection. To achieve its full potential, OAT requires a new generation of detection technologies that accommodate its unique features: weak signals, high signal directionality, and wide acoustic spectra.

In this talk, I will discuss two techniques recently developed by my group for the detection of acoustic signals in OAT. In the first technique, a novel acoustic detector was developed in a silicon-photonics platform, achieving a record-high resolution of <20 µm, previously achieved only in optoacoustic microscopy setups. In the second technique, we developed cyclic acoustic masks that enable the application of signal-pixel imaging, facilitating semi-isotropic resolution and sensitivity enhancement.
