“…The phase distribution over the whole panel is not the same, and thus the output light is not a coherence light source even though the bandwidth is very narrow. In order to obtain the coherence light source using LED, one LED bin with a pinhole is usually adopted [23][24][25][26][27]. The volume of the system increases due to the bulky light source.…”

Augmented reality (AR) provided extra information to the user by applying virtual image onto the real environment. There are many methods achieving AR. Holographic display is one of the potential ways due to its perfect 3D demonstration. Holographic display can provide the virtual 3D object with depth information. It can be realized an AR device with real 3D scene by combing holographic display. However, it is di cult to realize a compact holographic display with wide viewing angle and enough resolution. It limits holographic display to apply to AR. In this paper, we will discuss the requirements of holographic display based on the development of LCD, including resolution (ppi), viewing angle, image quality and backlight. We wish this article can provide preliminary direction for the LCD industry to develop AR technology using holographic display.

“…A metal halide lamp and three SLMs were used and they made a comparison with systems that use lasers as light sources. In subsequent papers by Sato and Takano [34], [35] a full-color electro-holographic 3-D display system employing LEDs is presented, and a virtual image reconstruction technique is studied. In addition, they proposed that direct and independent drives on LEDs through RGB waves bring ease to the adjustment of white balance, and a wide viewing angle can be attained.…”

True-3D imaging and display systems are based on physical duplication of light distribution. Holography is a true-3D technique. There are significant developments in electro-holographic displays in recent years. Liquid crystal, liquid crystal on silicon, optically addressed, mirror-based, holographic polymer-dispersed, and acousto-optic devices are used as holographic displays. There are complete electro-holographic display systems and some of them are already commercialized.

“…In other papers from the same group, a full-color electro-holographic 3D display system with LED illumination is reported. 44,45 Hahn et al proposed a holographic display system with a curved array of SLMs. 46 They used the the holographic stereogram technique for generating holograms.…”

"True 3D" display technologies target replication of physical volume light distributions. Holography is a promising true 3D technique. Widespread utilization of holographic 3D video displays is hindered by current technological limits; research activities are targeted to overcome such difficulties. Rising interest in 3D video in general, and current developments in holographic 3D video and underlying technologies increase the momentum of research activities in this field. Prototypes and recent satisfactory laboratory results indicate that holographic displays are strong candidates for future 3D displays. © 2010 SPIE
