Abstract
The influence of the diffraction limit on the field of
view of three-dimensional integral imaging (InI) systems is estimated by calculating
the resolution of the InI system along arbitrarily tilted directions. The
deteriorating effects of diffraction on the resolution are quantified in this
manner. Two different three-dimensional scenes are recorded by real/virtual
and focused imaging modes. The recorded scenes are reconstructed at different
tilted planes and the obtained results for the resolution and field of view
of the system are verified. It is shown that the diffraction effects severely
affect the resolution of InI in the real/virtual mode when the tilted angle
of viewing is increased. It is also shown that the resolution of InI in the
focused mode is more robust to the unwanted effects of diffraction even though
it is much lower than the resolution of InI in the real/virtual mode.
