Abstract
Photoacoustic endoscopy (PAE) is an emerging imaging modality which offers a
high imaging penetration and a high optical contrast in soft tissue. Most of the developed
endoscopic photoacoustic sensing systems use miniaturized contact ultrasound
transducers or complex optical approaches. In this work, a new fiber based detection
technique using speckle-analysis for contact-free signal detection is presented. Phantom
and ex-vivo experiments are performed in transmission and reflection-mode for
proof of concept. In summary, the potential of the technique for endoscopic photoacoustic
signal detection is demonstrated. The new technique might help in future
to broaden the applications of PAE in imaging or guiding minimally invasive laser
procedures.
