“…In this paper, a novel coherent backlight design is proposed that improves the DE to 4.3% which is more than 10 times higher than the previous result [11]. In our design, the first grating elongates beam spot in one dimension and the second grating expands the elongated beam in the orthogonal dimension to form a circular expanded beam with an area of ~0.7 cm 2 .…”

“…In another compact beam expander introduced by Revital et al [10], the output are multiple light spots which cannot be used as an entire plane wave. In our previous work, Xiong et al [11] proposed a coherent backlight system using a scattered wave to read a reflection hologram. Nevertheless, its diffraction efficiency (DE) is as low as 0.3%, which is a critical problem to resolve towards practical applications.…”

“…Multiple bulky optical elements used in current holographic displays usually lead to large volume. For instance, the collimating system (or laser beam expander) [17][18][19], which expands the laser beam to a proper size by lens groups, are too large for AR systems, especially for headmounted types.…”

We demonstrate a compact design for holographic augmented reality displays using two holographic optical elements (HOEs). In the method, the two HOEs, which are properly set in a flat‐panel form, function as a beam expander and see‐through eyepiece simultaneously. There is no traditional optical element in the system, resulting in a compact and lightweight design. The feasibility of this design is experimentally verified.

“…Among these 3D display techniques, holographic display is considered as an ultimate goal to provide realistic image of a real object or a scene, because it has the ability to reconstruct both the intensity and phase information of a true nature of an object or a scene, allowing the observer to perceive the light as it would be scattered by the real object itself without the need for a special eyewear [3]. Therefore, many research groups have studied the holographic displays of real 3D images, including photorefractive materials, holographic backlight [4], computer-generated holography (CGH) [5] and microelectro mechanical systems (MEMS) [6] etc. Optical holography based on the dynamic recording materials might be an effective way for the video-rate holographic display.…”
