Random mask encoding of multiplexed phase-only and binary phase-only filters

Abstract

In the formation of multiplexed filters, the phase-only and binary phase-only operations result in spurious cross terms and a nonlinear scaling. We use complementary random binary patterns having different pattern densities to encode the various functions within the multiplexed function. The orthogonality of these complementary masks permits separability of the phase-only or binary phase-only operations. By changing the pixel density of the random pattern, we can easily change the relative weights of the functions that compose the multiplexed filter. Experimental results are shown that demonstrate the effectiveness of this approach.
