WebOct 3, 2024 · Incoherent holographic 3D imaging with various light-wave information has also been researched to extend the applicability of IDH for structural investigation of an … 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.
