Abstract

We report on the implementation of spiral phase contrast imaging at multiple planes using forked-shaped defocus grating. The dual function of grating helps in simultaneous generation of multiple edge enhanced images corresponding to different depths. Present method is simple, direct and is applicable to coherent and incoherent imaging system.
