optimized digital HOE recording method that uses holographic printing technology and a computer-generated hologram (CGH) pattern to control the varying diffraction ef ficiency for each

Holographic optical element (HOE) is an optical component (mirror, lens, directional diffuser, etc.) that produces holographic images using principles of diffraction. HOE is most commonly used in transparent displays, 3D imaging, and certain scanning technologies.

2023年6月10日 · In this study, a 50 × 50 mm holographic optical element (HOE) with the property of a spherical mirror was recorded digitally on a silver halide photoplate using a wavefront printing method. It consisted of 51 × 96 hologram spots with each spot measuring 0.98 × 0.52 mm.

2023年6月15日 · In addition, to improve the uniformity of AR images restored through the HOE, we present an optimized digital HOE recording method that uses holographic printing technology and a computer-generated hologram (CGH) pattern to control the varying diffraction efficiency for each holographic element (hogel) as a minimum recording unit.

2023年6月16日 · This study uses a digital HOE screen that can fabricate and reconstruct augmented reality images of 1.17”, 1.76”, and 2.35” in a field of view of 28.07°, 41.11°, and 53.13°, respectively ...

The usability of the digital HOE as an optical component depends solely on its optical performance, which can be measured in two ways: one is by measuring the focusing characteristics of the HOE with a collimated beam, and the other is by measuring the wavefront using a Shack–Hartmann wavefront sensor [9,10]. This sensor can provide ...
