Abstract: Optoacoustic (photoacoustic) imaging assumes that the detected signal varies linearly with laser energy. However, nonlinear intensity responses as a function of light fluence have been suggested in optoacoustic microscopy, that is, within the first millimeter… read more here.

DOI: 10.1073/pnas.2207089119
Abstract: Significance Waves propagate diffusively through disordered media—such as biological tissue, clouds, or Earth’s crust—due to random scattering. Although most waves are reflected, only a tiny fraction carry information from deep inside the medium. These remitted… read more here.

Abstract: Selective excitation of a diffusive system's transmission eigenchannels enables manipulation of its internal energy distribution. The fluctuations and correlations of the eigenchannel's spatial profiles, however, remain unexplored so far. Here we show that the depth… read more here.
