Abstract

The investigation on zone plates is extended to the temporal case. By exploting the space-time duality between the paraxial difiraction of light in space and the linear dispersion of optical pulses, it presents the time-domain analog of multiple imaging formula at the replicas of the input pulse. The temporal system is created by using a linear chirp generator together with two dispersive delay lines. An example to illustrate the behavior of a temporal binary zone plate is considered.
