Fig. 3: PDG architecture and generation of handwritten numbers.
From: Photonic diffractive generators through sampling noises from scattering media
A, B Cascaded (A) and parallel (B) architecture of PDG. C The designed phase plates for each DPU layer. Upper and lower rows correspond to cascaded and parallel architecture, respectively. D Two selected handwritten number ('0' and '1') generation results. Cas. + Opt., cascaded architecture with optical readout; Cas. + Dig., cascaded architecture with digital readout; Par. + Opt., parallel architecture with optical readout; Par. + Dig., parallel architecture with digital readout. E Quantitative evaluation of handwritten number generation on 200 chosen experiment results.
