abstract: Planar sensor arrays have advantages when used for photoacoustic imaging: they do not require
the imaging target to be enclosed, and they are easier to manufacture than curved arrays. However, planar
arrays have a limited view of the acoustic field due to their finite size; therefore, not all of the acoustic waves
emitted from a photoacoustic source can be recorded. This loss of data results in artifacts in the reconstructed
photoacoustic image. A detection array configuration which combines a planar Fabry–Pérot sensor
with perpendicular acoustic reflectors is described and experimentally implemented. This retains the detection
advantages of the planar sensor while increasing the effective detection aperture in order to improve the
reconstructed photoacoustic image
