Abstract
Apparatus for streaking a beam of light employing a crystal in which an electromagnetic wave pulse induces a synthesized traveling lens. Surfaces on opposite sides of the crystal act as light reflectors to create multiple cross-reflections of the beam relative to the crystal, thus to enhance the lensing effect of the crystal. Production of the electromagnetic wave pulse is coordinated with impingement of a beam of light, and the geometry of parts is arranged whereby each coherent wave front in the beam, as it passes multiple times through the crystal, on each such passing encounters the same substantially constant lens condition which has been induced in the crystal.
