Abstract

A device and method for performing fluorescence imaging with digitally time reversed ultrasound encoded light, using a source of ultrasound waves, a coherent light source, a digital optical phase conjugation (DOPC) device comprising a camera and a spatial light modulator (SLM), a detector of fluorescence, and one or more computers, to obtain an output that at least approximates an interaction between a complete time reversed field, of all of the encoded light's fields, and the scattering medium.
