Abstract

A new idea of the holography process realization is developed. The method opens a way to the direct recording of information simultaneously on the spatial and temporal (spectral) characteristics of the field of light using the femtosecond pulses. The analysis of 1D- and 2D-cases under the conditions of an infinitely short (delta-shaped) pulse illumination is performed. The process of the hologram recording is similar to that in the conventional holography. The reference delta-wave interferes with the wave scattered by an object. No stationary interference pattern is formed, but the trace of the two-wave crossing point or line is recorded inside the photosensitive medium. The illumination of the hologram formed in such a process by the reference wave reconstructs the object wave, and vice versa. New property of the capability for the precise recording and reconstruction of the scatterer color is predicted. The time-encoding system for the holography is proposed, which facilitates the hologram recording and enables the femtosecond pulse amplification. Some fundamental problems of the ultrashort pulse diffraction are also considered.
