Broadband optical detection of ultrasound by two‐wave mixing in a photorefractive crystal
R. K. Ing,J.‐P. Monchalin +1 more
TL;DR: In this paper, a method which allows broadband (from typically 1 KHz) optical detection of ultrasound with large light gathering from a scattering surface is presented, where the wave scattered by the surface is mixed inside a BaTiO3 photorefractive crystal with a pump wave directly derived from the laser to provide a sideband free reference wave.
