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.

An auto‐stereoscopic back projection display using a RGB multi‐emitter laser illumination source and micro‐optics to provide a wider view is described. The laser optical properties and the speckle due to the optical system configuration and its diffusers are characterised.

An autostereoscopic head-tracked back projection display that uses an RGB laser illumination source and a fast light engine is described. Images are horizontally scanned columns controlled by a spatial light modulator that directs two or more images in the directions of the apposite viewers’ eyes.

A novel auto-stereoscopic 3D display system that forms dynamic exit pupils with the aid of a head-tracker is described Different views are displayed using time-multiplexing. Visible lasers, beam combiner, shaping and scanning optics and exit pupil control optics are discussed. It is estimated that 100 fL display brightness is achievable with about 3W per color of R, G and, B lasers.

An autostereoscopic 3D display based on direct-view RGB laser projection via a transparent display screen is presented. Dynamic exit pupils are formed at the target eye locations with the help of a pupil tracker.
