Temporal light control in complex media through the singular value decomposition of the time-gated transmission matrix (2202.01597v1)
Published 3 Feb 2022 in physics.optics and cond-mat.dis-nn
Abstract: The complex temporal behavior of an ultrashort pulse of light propagating through a multiply scattering medium can be characterized experimentally through a time-gated transmission matrix. Using a spatial light modulator, we demonstrate here, that injecting singular vectors of this matrix allows us to optimally control energy deposition at any controllable delay time. Our approach provides insights into fundamental aspects of multi-spectral light scattering and could find applications in imaging or coherent control.
