Mass production of holographic transparent components for augmented and virtual reality applications

Roadmap on holography

“…As of now no standard machinery for vHOE replication is available that can be ordered, like for example injection moulding machines replicating the surface grating of an optical disc from a master plate. Most recently, due to the availability of an industrial-scale photopolymer recording material, companies started to setup mass replication lines for vHOEs [85,[91][92][93][94][95]. The development of compact and easyto-use tuneable single frequency laser sources during the last decade is of great advantage [96,97].…”

Holographic Three-Dimensional Virtual Reality and Augmented Reality Display Based on 4K-Spatial Light Modulators

“…VR is widely used in various fields, such as architecture, gaming, and education, where it has a promising future in the development of VR. Compared to holographic displays, conventional optics present several disadvantages for near-to-eye 3D products for VR and AR [2]. Although 3D techniques are popular in current VR and AR applications, most 3D head-mounted displays (HMD) are based on stereoscopic 3D display technology, i.e., left and right eyes get two images with binocular parallax.…”
