“…However, in waveguide displays [11,12,14,15,16,17], for output a color image from a waveguide, one grating is sufficient for all three wavelengths. A schematic diagram of a waveguide projection suitable for both HUD and HMD is shown in Fig.…”

“…A schematic diagram of a waveguide projection suitable for both HUD and HMD is shown in Fig. 7 (this scheme is similar to that used in [16], but differs from it in the use of reflective holograms instead of transmission ones). The scheme includes a planar waveguide WG, a hologram H 1 for input the light beam PR from the projector into the waveguide, and a hologram H 2 for output light from the waveguide towards the observer OB.…”

“…Similarly an OE with holographic WF can be used in projection systems mounted on glasses (also known as HMDs, head-worn displays, wearable glasses, augmented reality glasses, smart glasses) [13,14,15,16,17]. HMDs were first developed for military aircraft (a projection system in a pilot's helmet).…”

The recently proposed optical elements containing semitransparent wavelike films embedded into the transparent material are investigated. Such optical elements do not distort a wave transmitted through them. Novel optical elements can be fabricated using well-known embossing methods. Their possible applications are discussed. The optical elements containing holographic wavelike films can be used for color holography, for augmented reality wearable glasses, as a beam combiner for head-up displays. The optical elements containing diffuse wavelike films can be used as an alternative for tinted car windows, instead of mirror-glass windows in high-rise buildings, for shop-windows, for one-way privacy windows, for printing images on eyeglasses. The scheme of a waveguide display with a single-layer holographic wavelike films is analyzed. The feasibility of the proposed applications is verified by estimation of the optical elements’ parameters and computer simulation, and measurements conducted on an experimental specimen.

“…In particular the modern versions of the Pepper's ghost illusion-invented by the English scientist John Henry Pepper in 1862-are often call "floating holograms" by the general public and the media. Pepper's ghost technique displays 2D images on the reflector to create the effect of floating virtual 3D images for the viewers [2][3][4]. The system typically uses transparent screens called half mirrors or foils as a way to project 2D images in the space.…”

Modern Pepper's ghost—“floating hologram”—systems generally use transparent screens called half mirrors or foils. this system must have the same screen size as the image size in order to display a large-sized image. Further, depth of the image can only be obtained from the distance between the screen and the display panel. These limitations can be overcome using holographic optical elements (HOE). HOE is made by recording as a refractive force of the lens with holographic material. In this study, the numerical values of the reconstructed images were theoretically analyzed through optical ray tracing, and the theoretical design of the reconstructed image size and depth plane was numerically measured and experimentally verified.
