Summary: The holographic optical element (HOE) lens is a compact imaging element fabricated by recording wavefront through interference. It has the advantages of wavelength and angle selectivity, arbitrary wavefront formation, making it promising in augmented reality display. However, the fabrication and design of a full-color HOE lens is challenging due to its sensitivity to wavelength and the need for optimization in the head-up display system.

Summary: In this Letter, a design and fabrication method for a full-color augmented reality (AR) optical system based on a freeform holographic optical element (HOE) is proposed. A point-by-point design method is used to generate the starting point of the system. The recording systems of the full-color HOE are designed based on the preliminarily optimized system. A joint optimization is conducted, considering the overall imaging performance, diffraction efficiency, constraints, and fabrication. A prototype is fabricated to validate the feasibility and effectiveness of the proposed method.

Summary: Egocentric augmented reality interfaces are becoming crucial for high precision activities in the peripersonal space. Traditional optical see-through displays face challenges in accurately registering computer-generated information with the real scene. This article proposes a new approach using a magnifier and dedicated calibration procedure to prevent parallax-related AR misregistration.

Summary: A freeform holographic optical element (HOE) is introduced to reduce the aberrations of a conventional lens HOE caused by off-axis recording and diffraction nature. A general characterization of the conjugate imaging equation of an elementary HOE is derived using scalar diffraction theory. The recording wavefronts of a freeform HOE are designed by determining each elementary HOE through the conjugate imaging equation. The predicted image position is consistent with finite ray-tracing method and the error caused by off-axis object points and different reconstruction wavelengths is effectively eliminated through coordinate transformation. A 3x3 tiling elementary HOE is designed based on this equation to eliminate distortion and astigmatism of the HOE imaging system. A holographic printer is recommended for fabricating this freeform HOE.

Summary: This paper presents a method for fabricating high diffraction efficiency full-color holographic optical elements (HOEs) using iterative exposure. The method achieved an average diffraction efficiency of 73.4% in a single photopolymer, the highest reported rate so far. The authors also simulated an augmented reality (AR) system using geometric optics and achieved a good color blending effect in a full-color AR display system.
