Optical focusing into scattering media via iterative time reversal guided by absorption nonlinearity
Abstract Guide star-assisted time-reversal enables deep optical focusing in scattering media such as biological tissue, overcoming the diffusion limit of light. However, in practice, guide stars formed using contrast agents or ultrasonic modulation naturally occupy regions much larger than the optic...
