Abstract

We propose a holographic printing technology for head-mounted display through practical design in hologram recording and reconstruction. Most head-mounted displays are designed based on waveguide type and analog holographic optical elements, resulting in disruption of the uniformity of the image because of the difference between the initial recording conditions and the source image. This problem can be solved using holographic printing technology to modulate different diffraction efficiencies for each holographic element. This study uses a digital holographic 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, at a distance of 53.33 mm from the eye. Moreover, augmented images are realized with higher diffraction efficiency than conventional methods, simplifying the design and facilitating mass production of uniformed products using digital holographic printing technology.
