Abstract
A streak camera is disclosed which includes an entrance slit forming a first end of the streak camera, the entrance slit having a width and height, an image capture device forming a second send of the streak camera, and an epsilon-near-zero (ENZ) slab defined by a bandgap energy and plasma frequency disposed within the streak camera, the ENZ slab configured to receive two beams with a predetermined delay therebetween, the two beams include i) a witness beam through the entrance slit at an incident angle θ, and ii) a trigger beam at substantially a normal incident angle, wherein the trigger beam applies energy at a level below the bandgap energy of the ENZ slab to thereby modify refractive index of the ENZ slab, and thus generate a modified witness beam at a time-varying exit angle φ(t) onto the image capture device.
