The optical setup for holographic projection on the scatterings in fluorescent liquids is presented. Such media can be used as volumetric screens for near-eye holographic displays, solving the problem of speckle noise and very small exit pupils in existing setups. Three different oils (canola, olive and engine oil) with 532 nm laser and tonic water with 405 nm laser are used for projecting holographic fields, the quality of such images is investigated. The laser wavelength is cut out from acquisition on a camera and only filtered fluorescent light is observed. The best and brightest results are obtained with engine oil. Full Text: PDF ReferencesX.

In this paper, we review liquid-crystal-on-silicon (LCoS) technology and focus on its new application in emerging augmented reality (AR) displays. In the first part, the LCoS working principles of three commonly adopted LC modes—vertical alignment and twist nematic for amplitude modulation, and homogeneous alignment for phase modulation—are introduced and their pros and cons evaluated. In the second part, the fringing field effect is analyzed, and a novel pretilt angle patterning method for suppressing the effect is presented. Moreover, we illustrate how to integrate the LCoS panel in an AR display system. Both currently available intensity modulators and under-developing holographic displays are covered, with special emphases on achieving high image quality, such as a fast response time and high-resolution. The rapidly increasing application of LCoS in AR head-mounted displays and head-up displays is foreseeable.

AbstractAs a promising candidate for next-generation mobile platforms, virtual reality and augmented reality have the potential to revolutionize the way we perceive and interact with various types of digital information. In the meantime, ultrathin planar liquid crystal polarization optics are enabling a new evolutionary trend in near-eye displays. A recent invited review paper published in eLight provides an insightful review on liquid crystal optical elements and their applications toward AR and VR.

This project realizes spatial augmented reality in public. We developed Glassless Augmented Display( GAD) which can show multiple different images to different direction simultaneously. Spatial augmented reality allows audiences to watch their preferred images and audios on public signage. It is a highly applicable technology configured by a consumer-based 4K liquid crystal display, superdirective speakers, a lenticular lens, and a multi-view image synthesizer implemented in a Unity application. We also proposed an application for GAD, which is called Simultaneous Spatial Shared Display (SSSD), which is implemented on Glassless Augmented Diaplay. SSSD enabled (1) simulmultiplex content display, (2) perspective correction, (3) without glasses and any sensing system, (4) directional audio for each content, and (5) attachable to conventional 2D display. These are used to display various contents, such as sports games and concerts, according to the movement of the audience.
