High speed deep tissue imaging system using multiplexed scanned temporal focusing

Abstract

A tissue imaging system includes a laser module for outputting a laser pulse, an optical delay module configured to split a laser pulse received from the laser module into a plurality of time-delayed sub-pulses, a telescope for delivering the sub-pulses from the optical delay module to a target volume and a photodetector configured to collect photons generated within the target volume in response to excitation of the target volume by the first and second sub-pulses. The system may further include a spatial multiplexing module configured to receive the temporally multiplexed laser pulse from the optical delay module and splitting the temporally multiplexed laser pulse into a plurality of sub-beams including a first sub-beam and a second sub-beam, wherein the first sub-beam and the second sub-beam are spatially separated with respect to a first image plane formed at a first depth within the target volume and with respect to a second image plane formed at a second depth within the target volume.
