HELIUM3D: A laser-scanned head-tracked autostereoscopic display

摘要

This paper describes the development of an autostereoscopic laser-based display that can serve several users who are able to move freely over a large area; it is intended for television applications and operates by tracking the positions of the viewers' heads and directing regions referred to as exit pupils towards their eyes. An exit pupil is a region where either a left or a right image is seen across the complete area of the screen. A description of the 60 and 120Hz prototypes developed is given. A set-up that does not show images but demonstrates the operation of the novel dynamic exit pupil formation system is also described,
