title: Phase retrieval of singular scalar light fields using a two-dimensional directional wavelet transform and a spatial carrier.
abstract: We evaluate a method based on the two-dimensional directional wavelet transform and the introduction of a spatial carrier to retrieve optical phase distributions in singular scalar light fields. The performance of the proposed phase-retrieval method is compared with an approach based on Fourier transform. The advantages and limitations of the proposed method are discussed.
