Photoacoustic phasoscopy for tissue characterization

Photoacoustic phasoscopy for tissue characterization

In this paper, a novel method named photoacoustic `phasoscopy' (PAP) is proposed to collect both scattered photons and induced photoacoustic wave to build a photo-acoustic phase spectrum, rather than conventional frequency spectrum, for biological tissue characterization,. PAP provides phase co...
