Abstract

The optical phase contrast technique in combination with camera technology is a promising ultrasound detection approach for photoacoustic imaging. However, sensitivity needs to be optimized to be competitive with piezo array detection approaches. This can be achieved without sacrificing resolution by substituting Fluorinert liquid for water. This liquid has a nearly four times larger piezo-optical coupling coefficient and a speed of sound (SoS) of 598 m/s. The overall performance of the proposed sensitivity improvement taking into account the spatial SoS inhomogeneities and reflecting walls in the reconstruction with the time-reversal method is examined in simulations and preliminary tests.
