WebOptical Kerr gating is widely used in ultrafast measurements ranging from pulse characterization to spectroscopy and microscopy. WebThe ultra-fast switching properties of the Kerr-gate can be used for optical imaging in medicine (see [2] and the references therein). Light reflected from the tissue (a strongly scattering medium) is then passed through a Kerr shutter in which (nonlinear) birefringence is induced by short infrared pulses.
