Patent number: 11199710Abstract: A beam scanner of a projector-based near-eye display includes a prismatic element with a reflective polarizer and a quarter-wave waveplate (QWP). The beam-folding prismatic element receives a polarized light beam from a light source and couples the beam to a tiltable reflector, e.g. a 2D tiltable MEMS reflector, for angular scanning the beam. The light beam impinging onto the tiltable reflector is separated from the light beam reflected from the tiltable reflector by polarization. The polarization-based separation is achieved by causing the light beam to propagate through the QWP before and after impinging onto the tiltable reflector. Upon double propagation of the light beam through the QWP, the beam changes its polarization to an orthogonal polarization, which enables its separation from the impinging beam. The beam scanner may receive multiple light beams from multiple light sources. A projector and a near-eye display based on such beam scanners are also disclosed.Type: GrantFiled: September 6, 2019Date of Patent: December 14, 2021Assignee: FACEBOOK TECHNOLOGIES, LLCInventors: Brian Wheelwright, Weichuan Gao, Stephen James McNally

Patent number: 11194087Abstract: A waveguide coupler may be coupled to a multi-beam light source, such as an array of superluminescent light-emitting diodes. The waveguide coupler includes a substrate having an end facet and a surface, e.g. a top flat surface, adjoining the end facet. At least one tilted reflector is supported by the substrate. A plurality of waveguides supported by the substrate extend between the end facet and the at least one tilted reflector. The at least one tilted reflector is configured to redirect light propagating in the plurality of waveguides to the surface of the substrate. In this manner, the waveguide coupler may provide an array of surface emission points on a substrate. All the surface emission points are disposed in one plane and may be suitably configured for subsequent joint collimation for use e.g. in a scanning projector display.Type: GrantFiled: May 9, 2019Date of Patent: December 7, 2021Assignee: Facebook Technologies, LLCInventors: Daniel Guenther Greif, Scott Charles McEldowney, Chadwick Brian Martin, Stephen James McNally

Patent number: 10685431Abstract: Methods for quantifying pupil swim are disclosed in order to compensate for the same. A target image, in one embodiment, is displayed on a display of a head mounted display (HMD). Images of the target image are captured from a plurality of positions relative to an optical axis of an optics block of the HMD at an exit pupil of the HMD. The target image includes features and differences between observed locations of the features and their expected locations absent the optics block are determined. From these differences, a wavefront of the optics block is reconstructed and distortion corrections for the optics block are generated using the wavefront. The distortion corrections, when applied to a virtual scene, add pre-distortion that is canceled by the optical imperfections of the optics block as light of the virtual scene with the pre-distortion passes through the optics block.Type: GrantFiled: July 17, 2019Date of Patent: June 16, 2020Assignee: Facebook Technologies, LLCInventors: Ying Geng, Stephen James McNally, Brett Joseph Bryars, Scott Charles McEldowney, Alexander Jobe Fix, Douglas Robert Lanman
