A simple method for producing multiple images is reported by recording a lensless Fourier transform hologram of the master object using a holographic grating. Relations for optimizing reference-to-object beam intensity ratio are derived in order to retain linearity and efficiency of the hologram. One of the advantages of the technique is that the same grating can be used for the objects of different sizes.
