Distributed Edge-Enhanced Imaging With a Fractional Spiral Phase Filter Using Random Light

A gradual edge-enhanced ghost imaging method with pseudo-thermal light is proposed in both the theory and experiment. In the experiment, a phase object and fractional spiral phase filter are placed symmetrically in the imaging plane of the pseudo-thermal light source in the distributed test and refe...
