On a method of conversion and reconversion of spatial into temporal frequencies.
A method is presented for recording into the temporal domain the information contained in a light wavefront. This is achieved by making the wavefront interfere with the field from a moving point-light source and integrating the intensity of the interference pattern in space with an extended photodetector. In the inverse process, the time dependent signal is converted, with a suitable arrangement, in a hologram. Possible applications to holograms of steady or moving objects are considered. An experiment supporting the theoretical conclusions is presented.
