Abstract: A parallel beam flexure mechanism (“PBFM”) for adjusting an interpupillary distance (“IPD”) of an optical device is disclosed. The PBFM includes a plurality of flexures, a mounting platen, an optical payload, and a horizontal translation mechanism. The mounting platen has a first end and a second end, where the mounting platen is attached to a first set of flexures that are in a parallel arrangement to a second set of flexures attached to a frame of an optical device, such as a head mounted display. The optical payload and horizontal translation mechanism are attached to the mounting platen, where the horizontal translation mechanism is configured to translate the mounting platen in a horizontal direction by bending the flexures, thereby adjusting the IPD of the optical device.

Abstract: In embodiments of laser illumination scanning, an imaging unit includes a linear array of spatial light modulators that direct light in a direction perpendicular to an imaging scan direction. The lasers each emit the light through a diffractive optic that uniformly illuminates the spatial light modulators, and a scanning mirror then scans the spatial light modulators to generate a two-dimensional image for display. The lasers can include red, green, and blue lasers for RGB illumination of the spatial light modulators, which can be implemented as reflective liquid crystal on silicon (LCOS), transmissive LCOS, or as micro-electro-mechanical systems (MEMS) mirrors.

Abstract: In embodiments of pixel opacity for augmented reality, a display lens system includes a first display panel that displays a virtual image generated to appear as part of an environment viewed through optical lenses. A second display panel displays an environment image of the environment as viewed through the optical lenses, and the environment image includes opaque pixels that form a black silhouette of the virtual image. The display lens system also includes a beam-splitter panel to transmit light of the environment image and reflect light of the virtual image to form a composite image that appears as the virtual image displayed over the opaque pixels of the environment image.

Abstract: A system and method are disclosed for providing uniform color distribution of light emitted from a light source to an eye box in a near eye display (NED). An example of the system and method uses an optical element including two or more waveguides optimized to different colors of the visible light spectrum. The optical element further includes one or more polarization state generators for controlling the polarization of light incident on the waveguides to facilitate coupling of light into a matched waveguide, and to impede coupling of light into unmatched waveguides.

Abstract: In embodiments of wearable display device calibration, a first display lens system forms an image of an environment viewed through the first display lens system. A second display lens system also forms the image of the environment viewed through the second display lens system. The first display lens system emits a first reference beam and the second display lens system emits a second reference beam. The first display lens system then captures a reflection image of the first and second reference beams. The second display lens system also captures a reflection image of the first and second reference beams. An imaging application is implemented to compare the reflection images to determine a misalignment between the first and second display lens systems, and then apply an alignment adjustment to align the image of the environment formed by each of the first and second display lens systems.
