Improving Photoacoustic-guided Focusing in Scattering Media by Spectrally Filtered Detection
TL;DR: By monitoring the speckle pattern evolution during the optimization process with a CCD camera, it is experimentally confirmed that such optimization leads to a smaller optical focus than what would be obtained by optimizing lower frequencies of the photoacoustic feedback.
