Visible-light metalens far-field nanofocusing effects with active tuning of focus based on MIM subwavelength structures used in an integrated imaging array.

We propose a structure of a far-field nanofocusing metalens with focal shifting that is actively tuned at visible wavelengths. Surface plasmon polaritons (SPPs) can be excited by the metal-insulator-metal (MIM) subwavelength structure at visible wavelengths. The coherent interference of SPPs emitted by subwavelength nanostructures can form a nanoscale focus.

Motion parallax and lossless resolution autostereoscopic 3D display based on a binocular viewpoint tracking liquid crystal dynamic grating adaptive screen.

The autostereoscopic 3D display has two important indicators, both the number of viewpoints and display resolution. However, it's a challenge to improve both the viewpoint and the resolution. Here, we develop a fixed-position multiview and lossless resolution autostereoscopic 3D display system that includes the dynamic liquid crystal (LC) grating screen.

Numerical simulation and experimental verification of a dense multi-view full-resolution autostereoscopic 3D-display-based dynamic shutter parallax barrier.

We came up with a practical setup and simulation for building a glassless autostereoscopic 3D display system based on the concept of "eye space" with a dynamic shutter parallax barrier. "Eye space" is designed based on geometrical optics to get a multi-view as much as possible by adjusting the width of the slit and parallax barrier dynamically. The dynamic parallax barrier is placed in front of the display screen to form the shutter screen.
