WebIncoherent Holography Incoherent holography combines the holographic principle to retrieve amplitude and phase information via interferometric means with shearing … WebWe present a new method for recording digital holograms under incoherent illumination. Light is reflected from a 3D object, propagates through a diffractive optical element (DOE), and is recorded by a digital camera. Three holograms are recorded sequentially, each for a different phase factor of the DOE.
