Abstract
An arrangement for effecting holographic recording of information occurring in the form of electrical signals, wherein a coherent object wave which has been pulse modulated by an electrical signal is to be recorded, and a coherent reference wave is used to produce a unidimensional hologram upon a moving photosensitive storage medium, and a divergent reference wave and a convergent object wave, or a convergent reference wave and a divergent object wave, or two convergent reference and object waves or two divergent object and reference waves are used. The present invention defines the equation for the position of the reference and object points so as to provide accuracy in reproducing the holograms.
