Holographic analysis of dispersive pupils in space–time optics

Abstract
Extension of space–time optics to objects whose transparency is a function of the temporal frequency ν = c/λ is examined. Considering the effects of such stationary pupils on white light waves, they are called temporal pupils. It is shown that simultaneous encoding both in the space and time frequency domains is required to record pupil parameters. The space–time impulse response and transfer functions are calculated for a dispersive nonabsorbent material. An experimental method providing holographic recording of the dispersion curve of any transparent material is presented.
