A method of computing a computer generated hologram (CGH) for use in displaying a holographic image of a replay object. The method of generating a first computer generated hologram corresponding to the desired replay object (step 1 ); subdividing the first computer generated hologram into a plurality of blocks, each representing a sub CGH (step 2 ); for each block or sub CGH, calculating the corresponding replay sub-image hereafter called target wavefront data set (step 3 ); and generating for each target wavefront data set a second constrained modulation computer generated hologram wherein that second CGH is modulated within constrained values (step 5 ); and combining the plurality of second constrained modulation computer generated holograms to provide a third complete constrained modulation computer generated hologram (step 6 ).
