Abstract

Various nonlinear temporal gating techniques [e.g., 1], which rely on the cross-correlation between signal and gating pulses (or auto-correlation if gating the pulse with itself), effectively address the slow response times of optical sensors. These methods have facilitated significant advancements in applications such as time-resolved spectroscopy and microscopy, FROG, as well as ballistic photon imaging through scattering media.
