In this work, a universal algorithm for designing a panoramic annular lens (PAL) system free
from stray light is proposed. The impact of a given stray light path to the optical system could …

The way we interact with the world is constantly evolving thanks to developments in virtual
reality (VR) and augmented reality (AR) technologies. AR has been extensively employed in …

The freeform imaging system is playing a significant role in developing an optical system for
the automotive heads-up display (HUD), which is a typical application of augmented reality …

A two-dimensional geometrical waveguide enables ultra-thin augmented reality (AR) near-
eye display (NED) with wide field of view (FOV) and large exit-pupil diameter (EPD). A …

Waveguide displays have been shown to exhibit multiple interactions of light at the in-
coupler diffractive surface, leading to light loss. Any losses at the in-coupler set a …

The paper analyzes the image quality in augmented reality display based on holographic
waveguides. Brightness, brightness non-uniformity, image noise, etc., depend on the …
