Three-dimensional display system using near on-axis, phase-only digital holography

Abstract

We propose a method for carrying out three-dimensional (3D) display based on single-shot digital holography. The 3D display is realized from a digital hologram (DH) by displaying the complex function recovered through the constrained optimization approach on a phase-only spatial light modulator (SLM). A DH of a multiplane object is recorded in a near on-axis configuration, and the complex function corresponding to the object in the hologram plane is recovered. The recovered function is converted into a phase-only function, and it is displayed on a phase SLM. The optical reconstruction through simple diffraction from the SLM reproduced the 3D scene, and the image reconstructed at each plane has been observed.
