Paper Abstract

An improved computer-generated hologram recording technique for 12x128-pixel binary spatial light modulators is presented. The method is based on a diagonal coding previously introduced, but instead of using 4x4 supercells as in the previous case, the size of the supercell has been reduced to 2x2 pixels. Experimental results from computer simulations show that high-speed rotation-invariant recognition of simple shapes is possible with such holograms.
