Multi-plane Holographic Projection Using Programmable Fresnel Phase Lenses
A method to achieve multi-plane holographic projection using programmable Fresnel phase lenses was investigated. A multi-plane holographic projection system was developed with liquid crystal on silicon phase modulator. First, the programmable Fresnel phase lenses were substituted for the Fourier lens, in addition, the phase of Fresnel phase lenses were added to the computer generated phase holograms. Then based on the principles of time division multiplexing and space division multiplexing, two different methods combined programmable Fresnel phase lenses and phase holograms displayed on a phase modulating spatial light modulator were presented. Finally, the method to acquire dynamic 360°viewing-angle images corresponding to the object rotation in each image plane of multi-plane holographic projection was discussed. Experimental results show that holographic projection images could be recorded at different distances such as 500, 800, 1 100 and 1 400 mm from the LCOS. Dynamically change the focal length offered by the programmable Fresnel phase lenses, multi-plane holographic projection could be performed.
