Patent number: 8491136Abstract: A light guide of the tapered-waveguide type includes an input slab for expanding a projected image between an input end and an output end; and a tapered output slab arranged to receive rays from the said output end of the input slab, and to emit them at a point on its face that corresponds to the angle at which the ray is received. The taper is calculated so that all rays injected into the input end undergo the same number of reflections before leaving the output face. The thickness of the input slab light guide is greater in the transverse direction away from the center line, so that light travelling at the critical angle from the input face of the slab waveguide towards the output waveguide bounces the same number of times in the input slab, regardless of its fan-out angle, in order to further reduce image distortion.Type: GrantFiled: April 9, 2012Date of Patent: July 23, 2013Assignee: Microsoft CorporationInventors: Adrian Travis, Timothy Andrew Large, Neil Emerton

Patent number: 8348440Abstract: The invention relates to a vision system for representing synthetically generated images for the stimulation of night vision appliances, especially in training simulators for driving or flight training, and lighting and observation operations in night vision conditions. Said system comprises an image generator (17) for generating image signals of a synthetic image, at least one projector (16) which is fed with the image signals and used to project the image onto at least one projection screen (11), and a night vision appliance (15) for visualizing the projected image. The aim of the invention is to create a technically less complex, cost-effective visual system, whereby the projected image is visualized through the night vision appliance (15) in an undisturbed manner when the night vision appliance is stimulated correctly.Type: GrantFiled: September 21, 2005Date of Patent: January 8, 2013Assignee: Rheinmetall Defence Electronics GmbHInventors: Hubert Burggraf, Wilfried Plass, Michael Paschold, Hans Born
