Abstract

We detail a method for the accurate encoding of complex wavefields in low-cost, off-the-shelf spatial light modulators capable of amplitude modulation. We assess the accuracy of our encoding scheme by producing a collection of arbitrary nondiffracting beams and evaluating their propagation characteristics when compared to those predicted by the theoretical model. The angular spectra of the beams produced using this approach is also measured and found consistent with theory.
