Paper Abstract

Detection of acoustic waves is the cornerstone of photoacoustic tomography (PAT). Detection has conventionally been performed mechanically using ultrasonic transducers, or optically by interferometric techniques. We propose an interferometric detection scheme using low coherence interferometry (LCI) and discuss the challenges, advantages and limitations of applying this technique to photoacoustics.
