Paper Abstract

It is well known that a coherently illuminated conventional lens-based optical system can be used to display either the spatial frequency spectrum or the image of an object which are located in different planes. But, to get both of them in a single plane is difficult. We have suggested a simple method of achieving this. Two holographic optical elements (lens) of two different focal lengths are multiplexed on the same hologram, one focal length being double of the other. The multiplexed holographic lens is utilized to display the image and the spectrum of an object in a single plane in two spatially separated positions. Preliminary experimental results are presented.
