Main Results:

  • Continuous parallax is retained when lenslet lateral resolution matches display resolution.
  • Lenslet aberration-limited resolution acts as a low-pass reconstruction filter.
  • A condition for optimal continuous parallax was derived based on pixel width and lenslet spot size.

Conclusions:

  • Matching lenslet and display resolution is key for preserving continuous parallax.
  • The derived condition provides a guideline for designing high-fidelity 3D integral displays.
  • This research contributes to advancing the quality of 3D imaging systems.
