Foveated holographic near-eye display with geometric phase lens and camera feedback

In this paper, we introduce a novel holographic foveated near-eye display, leveraging the capabilities of two reflective-type phase-modulating spatial light modulators (SLMs). Reconstructed holographic three-dimensional images are imaged with different magnifications by polarization optics, creating a peripheral and foveal holographic three-dimensional image. The core element of the proposed system is a geometric phase (GP) lens, having different optical power based on the circular polarization state of the incident light. The proposed optical system has a compact form factor because the GP lens has only a millimeter thickness and two SLMs can be placed very close to the polarizing beam splitter.
