Adaptive Randomization of Pixel Pattern for Suppressing Higher Orders of Diffraction

Not Accessible

Your library or personal account may give you access

Abstract

Randomization of pixel positions in the computer-generated hologram is proved to suppress the higher diffraction orders in the image reconstruction. In order to prevent the possible resultant decrease of the SNR and improve the diffraction efficiency of the phase pattern displayed on the SLM, correction algorithms are proposed.
