“…Recently, many researchers have studied the holographic waveguide structures [1][2][3][4][5][6][7][8], whose in-coupling and out-coupling optical elements are the reflection volume holographic grating (VHG) with mirror symmetry. Both of the in-coupling and out-coupling VHGs are laminated on the both surfaces of waveguide.…”

A double-layer holographic waveguide, which is made from the acrylate photopolymers, is proposed for the see-through augmented reality. The most significant contribution is the integration of ocular lenses into the waveguides. The waveguide design, imaging principle, optical simulations, and fabrication methods are introduced. In our experiments, a prototype with a diagonal field of view of 30° is demonstrated. Compared to other multi-layer waveguides, our solution could offer a more compact form factor, which is essential for wearable devices.

Waveguide display is a common augmented reality (AR) solution. In traditional waveguide display systems, the design of the couplers and the design of the collimators are separated. In order to achieve high imaging resolution under a large field of view, complex collimating lens groups are often required. In this work, a waveguide display scheme based on the coupling-collimation system is proposed. This system consists of a freeform liquid crystal diffractive optical element on the waveguide and a freeform element outside the waveguide, replacing the conventional in-coupler and collimator. Through the overall optimization of the coupling-collimation system, a wide-field-of-view and high-resolution waveguide display can be realized with a simple and compact structure. We demonstrate the effectiveness and superiority of this scheme by exemplifying several design results. The proposed scheme is expected to facilitate the design of waveguide displays with higher performance.
