Sparse CGH techniques

Caption

Examples of sparse CGH methods. a, The blue 3D curve and point are close to the wavefront recording plane, only affecting nearby coefficients delineated in the red regions. This contrasts with the hologram plane H, where all pixels are affected. b, A point-spread function and its corresponding sparse 2-level Daubechies-4 wavelet transform. c, Accurate phase-added stereograms on 16×16 coefficient blocks with redundancy 2.
