Abstract
An enlargement method of reconstruction angle by time-sharing tilted
illumination in a three-dimensional (3D) display system based on wavefront
modulation is presented. In a recording system, an array of phase-shifting
interferometer is used for recording the wavefront data from 3D object in
wide angle. In a reconstruction system, single display device such as
spatial light modulator is illuminated with tilted plane waves for wide
angle reconstruction. Tilted illumination causes the spatial shift of
reconstructed 3D object according to the illumination angle. We propose a
method to reduce the spatial shift by changing the reconstruction position
around display plane. Experimental and numerical results are
presented.
