Abstract

The problems of spatial diffraction and optical dispersion in the time domain was extended by analogy to optical ultrafast pulse filtering. An analog setup in the 4-f spatial-filter configuration is proposed, and several applications such as the temporal signal convolver or correlator and the joint transform processor are suggested, followed by ways to generate the temporal filter. The implementation aspects and an example of the speed superiority of this approach are also discussed.
