Near-perfect hologram reconstruction with a spatial light modulator
... holograms usually exhibit a huge intensity contrast of several orders of magnitude between their central zero-order Fourier component, and the outer higher-order components. Techniques which shape such a high contrast amplitude profile with an absorptive mask from a uniform beam sacrifice most of th ...
