通过计算三维积分成像系统沿任意倾斜方向的分辨率,估算了衍射极限对系统视场的影响。用这种方法量化了衍射对分辨率的恶化影响。采用实/虚和聚焦成像模式记录两种不同的三维场景。对记录的场景在不同的倾斜平面上进行了重建,并对系统的分辨率和视场进行了验证。结果表明,在实/虚模式下,随着视角的增大,衍射效应严重影响了InI的分辨率。结果还表明,聚焦模式下的InI分辨率比实/虚模式下的InI分辨率低得多,但对不需要的衍射影响有更强的鲁棒性。

英文摘要:
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.
