Rajwinder Singh Brar; Phil Surman; Ian Sexton; Richard Bates; Wing Kai Lee; Klaus Hopf; Frank Neumann; Se Day; Eero Willman

The construction and operation of two laser-based glasses-free 3D (autostereoscopic) displays that have been carried out within the European Union-funded projects MUTED and HELIUM3D is described in this paper. Both use a multi-user head tracker to direct regions viewers referred to as exit pupils to viewers eyes. MUTED employs a direct-view LCD whose backlight comprises novel steering optics and in HELIUM3D image information is supplied by a horizontally-scanned fast light valve whose output is controlled by a spatial light modulator (SLM). The principle of operation, construction and results obtained are described.

Multi-viewer autostereoscopic display with dynamically addressable holographic backlight

Edward Buckley; Alexander D. Corbett; Phil Surman; Ian Sexton; Klaus Hopf; Frank Neumann

— The Multi-User 3-D Television Display (MUTED), designed to provide three-dimensional television (3-D TV) by the display of autostereoscopic imagery to multiple viewers, each of whom should enjoy freedom of movement, is described. Such an autostereoscopic display system, which allows multiple viewers simultaneously by the use of head tracking, was previously demonstrated for TV applications in the ATTEST project. However, the requirement for a dynamically addressable, steerable backlight presented several problems for the illumination source. The MUTED system demonstrates significant advances in the realization of a multi-user autostereoscopic display, partly due to the provision of a dynamic backlight employing a novel holographic laser projector. Such a technology provides significant advantages in terms of brightness, efficiency, laser speckle, and the ability to correct for optical aberrations compared to both imaging and scanned-beam projection technologies.

This paper presents a laser-based auto-stereoscopic 3D display technique and a prototype utilizing a dual projector light engine. The solution described is able to form dynamic exit pupils under the control of a multi-user head-tracker. A prototype completed recently is able to provide a glasses-free solution for a single user at a fixed position. At the end of the prototyping phase it is expected to enable a multiple user interface with an integration of the pupil tracker and the spatial light modulator.

MUTED: Multi-user 3-D display.

Rajwinder Singh Brar; Phil Surman; Ian Sexton; Klaus Hopf

Abstract— Research described in this paper encompasses the design and building of glasses-free (autostereoscopic) displays that utilize a direct-view liquid-crystal display whose backlight is provided by a projector and novel steering optics. This is controlled by the output of a multi-user head-position tracker. As the displays employ spatial multiplexing on a liquid-crystal-display screen, they are inherently 2-D/3-D switchable with 2-D being achieved by simply displaying the same image in the left and right channels. Two prototypes are described in this paper; one incorporating a holographic projector and the other a conventional LCOS projector. The LCOS projector version addresses the limitations of brightness, cross-talk, banding in the images, and laser stability that occur in the holographic projector version. The future development is considered and a comparison between the prototypes and with other 3-D displays is given.

Latest developments in a multi-user 3D display

Phil Surman; Ian Sexton; Richard Bates; Wing Kai Lee; Klaus Hopf; Triantaffilos Koukoulas

De Montfort University, in conjunction with the Heinrich Hertz Institute, is developing a 3D display that is targeted specifically at the television market. It is capable of supplying 3D to several viewers who do not have to wear special glasses, and who are able to move freely over a room-sized area. The display consists of a single liquid crystal display that presents the same stereo pair to every viewer by employing spatial multiplexing. This presents a stereo pair on alternate pixel rows, with the conventional backlight replaced by novel steering optics controlled by the output of a head position tracker. Illumination is achieved using arrays of coaxial optical elements in conjunction with high-density white light emitting diode arrays. The operation of the steering and multiplexing optics in the prototype display are explained. The results obtained from a prototype built under the European Union-funded ATTEST 3D television project are described. The performance of this model was not optimum, but was sufficient to prove that the principle of operation is viable for a 3D television display. A second prototype, incorporating improvements based on experience gained, is currently under construction and this is also described. The prototype is capable of being developed into a display appropriate for a production model that will enable 3D television to come to market within the next ten years. With the current widespread usage of flat panel displays it is likely that customer preference will be for a hang-on-the-wall 3D display, and this challenge will be met by reconfiguring the optics and incorporating novel optical addressing techniques.

Flat-Concave Dual-Mirror Configuration Design for Upright Projection-Type Ultrashort Throw Ratio Projectors

Zhenfeng Zhuang; Phil Surman; Xiao Wei Sun; Feihong Yu

An off-axis flat-concave dual-mirror (FCDM) configuration for an ultrashort focal length projection lens based on the digital light processor (DLP) upright projection-type projector is proposed in this paper. This projection lens is composed of two lens groups: the FCDM system and the relay optical system. The flat mirror and the contour of the concave mirror are determined according to the relationship between the chief ray from the exit pupil of each field of view (FOV) and the corresponding assigned position on the screen. A curved image is formed between exit pupil and concave mirror, aiming to correct field curvature. The second lens group consists of a set of conventional refractive lenses which convert a curved object onto the image panel. Based on this method, a projection lens with an ultrashort throw ratio (TR) of 0.34, including a full FOV 139.8 ° and distortion of less than 1%, is designed. Additionally, the colorimetric performance, uniformity, optical efficiency and size of the designed projector are analyzed. Results show that the proposed projector system with high optical performance is compact and suitable for household or educational applications.

Stereoscopic and Autostereoscopic Displays

Phil Surman

This chapter covers the state of the art in stereoscopic and autostereoscopic displays. The coverage is not exhaustive but is intended that in the relatively limited space available a reasonably comprehensive snapshot of the current state of the art can be provided. In order to give a background to this, a brief introduction to stereoscopic perception and a short history of stereoscopic displays is given. Holography is not covered in detail here as it is really a separate area of study and also is not likely to be the basis of a commercially viable display within the near future.

Solving the 3D Problem—The History and Development of Viable Domestic

Phil Surman; Klaus Hopf; Ian Sexton; Wing Kai Lee; Richard Bates

Domestic television and video display is central to one of the largest consumer electronics markets in the world and the prize for developing a technically capable, and commercially viable domestic-suitable 3D video display system is likely to be great. Producing such a domestic 3D video system places great demands on innovation, research and development, but with recent advances in the enabling technologies such displays are now within our grasp. This paper starts by giving a brief history of the many attempts to produce a viable domestic 3D video display, illustrating the pioneers who first initiated research on 3D domestic displays. This paper then outlines and discusses the essential requirements that would be necessary to fulfil viewer expectations of a viable and usable domestic 3D video display. These demands are then placed in the context of the historical attempts to produce viable 3D displays, showing how these attempts have informed current thinking by outlining the problems of each technology approach. The paper then goes on to describe possible contemporary approaches to producing domestic 3D video displays, discussing the current viability of each, and showing that although there are many current solutions, these are often not suitable for domestic use. The paper then shows the development, based on historical work and contemporary thinking and technology, of viable 3D domestic video displays for both single viewer use and multiple viewer use that are hoped will fulfil the demands of domestic use. The paper summarises with the prediction that within the next 10 years we will see domestic 3D video displays readily available and accepted by the market place.

Multi-user 3D display employing coaxial optics

Phil Surman; Ian Sexton; Richard Bates; Wing Kai Lee; Kam Chuan Yow

De Montfort University (DMU) has developed an autostereoscopic display that is targeted specifically at television applications. The display is capable of supplying 3D images to multiple viewers who are not required to wear special glasses, and who are able to move freely over a room-sized area. It operates by producing regions (exit pupils) in the viewing field where either a left or a right image is seen. The positions of the exit pupils are steered to the viewers’ eyes by the use of head tracking. The DMU display consists of an LCD whose conventional backlight is replaced by a steerable optical configuration that is capable of producing several pairs of exit pupils. Left and right images are produced on alternate pixel rows of a single UXGA LCD. This spatial image multiplexing is achieved by the use of a lenticular sheet located between the steering optics and the LCD. The steering optics can produce exit pupils over a large area, but without the aberration and coloration effects associated with other methods. This is achieved using arrays of coaxial lenses in conjunction with high-density white LED array sources.
