Computer-generated holography with ordinary display
Summary: Researchers have developed a method for computer-generated holography (CGH) using incoherent light emitted from a mobile phone screen. The technique involves synthesizing a hologram cascade by solving an inverse problem related to incoherent light propagation. The team demonstrated a 3D color image reproduction using a two-layered hologram cascade composed of an iPhone and a spatial light modulator.
