Abstract
Integral imaging is a promising technology for 3-D TV and 3-D display.
In this paper, a theoretical analysis of 3-D integral imaging systems is performed
in the frame of the Wigner distriburion formalism. It is shown that the entire
intensity distribution in the pick-up image plane of these systems can be
obtained from a single 2-D Wigner distribution function of a single lenslet
pupil. This result reveals the Wigner distribution function as a powerful
tool for analysis of 3-D integral imaging systems with different pupil functions.
As an example, the extension of the depth of field of an integral imaging
system with lenslets having amplitude modulation (central obscuration) is
proposed.
