“…Current methodologies for generating virtual images with a clear, optical see‐through pass in a glasses‐like form factor can be broadly categorized into two groups: waveguide‐based and non‐waveguide‐based solutions. Non‐waveguide‐based AR displays encompass a variety of technologies, including bird‐bath optics, holographic displays, retinal projection, and pin mirror optical combiners 11 . Waveguide‐based AR displays employ either refractive waveguides, which use cascaded mirrors, 12 or diffractive waveguides, which use various diffraction gratings such as surface relief gratings (SRG), volume Bragg gratings (VBG), and PVG.…”

Augmented reality (AR) has gained enormous popularity and acceptance in the past few years. AR is indeed a combination of different immersive experiences and solutions that serve as integrated components to assemble and accelerate the augmented reality phenomena as a workable and marvelous adaptive solution for many realms. These solutions of AR include tracking as a means for keeping track of the point of reference to make virtual objects visible in a real scene. Similarly, display technologies combine the virtual and real world with the user’s eye. Authoring tools provide platforms to develop AR applications by providing access to low-level libraries. The libraries can thereafter interact with the hardware of tracking sensors, cameras, and other technologies. In addition to this, advances in distributed computing and collaborative augmented reality also need stable solutions. The various participants can collaborate in an AR setting. The authors of this research have explored many solutions in this regard and present a comprehensive review to aid in doing research and improving different business transformations. However, during the course of this study, we identified that there is a lack of security solutions in various areas of collaborative AR (CAR), specifically in the area of distributed trust management in CAR. This research study also proposed a trusted CAR architecture with a use-case of tourism that can be used as a model for researchers with an interest in making secure AR-based remote communication sessions.

“…As a method of implementing a technique of DOF extension, there is the pin-mirror array type AR optics 36 , 37 . The pin-mirror-based technology has the advantage of being able to implement a compact optical system and expand the eye-box, but the use of the pin-mirror array also has the opposite effect of reducing the DOF expansion effect.…”

The 3D display device shows an image with depth information. Conventional 3D display devices based on binocular parallax can focus accurately only on the depth of a specific screen. Because the human eye has a narrow depth of field (DOF) under normal circumstances, 3D displays that provide a relatively wide range of virtual depth areas have limitations on the DOF where clear 3D images are seen. To resolve this problem, it is necessary to find the optical conditions to extend the DOF and analyze the phenomena related to it. For this, by using the Rayleigh criterion and the Strehl ratio, a criterion for this extension of the DOF is suggested. A practical optical structure that can effectively extend the DOF is devised using a flat panel display. This optical structure could be applied to AR, VR, and MR in the field of near-eye displays. From the results of this research, the fundamental optical conditions and standards are proposed for 3D displays that will provide 3D images with extended DOF in the future. Furthermore, it is also expected that these conditions and criteria can be applied to optical designs for the required performance in the development of 3D displays in various fields.
