Complementary computer generated holography for aesthetic watermarking
Optics Express, 2012 We present herein an original solution for the watermarking of holograms in binary graphic arts without unaesthetic diffractive effect. It is based on the Babinet principle of complementary diffractive structures adapted to Lohmann-type computer generated holograms.

Computer-generated holography with ordinary display [PDF]
Optics Letters, 2023 We propose a method of computer-generated holography (CGH) using incoherent light emitted from a mobile phone screen. In this method, we suppose a cascade of holograms in which the first hologram is a color image displayed on the mobile phone screen. The hologram cascade is synthesized by solving an inverse problem with respect to the propagation of ...
