Abstract: A near-eye display system employs a low-amplitude, low-frequency micro-electromechanical system (MEMS) mirror in series with a higher-amplitude, higher-frequency resonant MEMS mirror to rotate at a reduced amplitude and frequency with respect to the resonant MEMS mirror redistribute illumination pulses or pixels at the extents of a sinusoidal angular scan pattern of the resonant MEMS mirror.

Abstract: Systems and methods to reduce diffraction-angle effects, such as instances of double-bounces and bounce separation spacing effects in a laser projection system including an optical engine with laser diodes configured to emit light beams of different wavelengths and a beam combiner having a reflective surfaces each configured to receive one of the light beams from one of the laser diodes and to reflect the received light beam such that an edge of the reflected light beam lies on a tangent common to the other light beams reflected from the other reflective surfaces. The laser projection system may be implemented in head-mounted display (HMD) including a waveguide having an incoupler to receive the combined light beam, where an edge of the incoupler corresponds to the tangent on which the edges of the plurality of light beams are aligned.

Abstract: A micro-projection system for use in small electronic devices can benefit from an optical assembly equipped with light-absorbing apertures. The light-absorbing apertures can aid in reducing or eliminating stray light and associated ghost images from appearing on the display of the projection system. Modular units that include laminated stacks of such apertures, along with spacers, can be inserted into air gaps within the optical assembly. Such stacked units can be made cost effective to manufacture in high volume.

Abstract: Systems and methods for incoupling light into a waveguide. A system includes a transfer optic and an optical scanner being configured to receive light from an optical engine. The optical scanner includes a first scan mirror positioned close to the transfer optic. The system further includes a waveguide with an incoupler positioned close to the transfer optic, which is configured to direct the light from the optical engine to the first scan mirror and to transmit light reflected from the first scan mirror to one of a second scan mirror or the incoupler of the waveguide.

Abstract: Display systems, such as near eye display systems or wearable heads up displays, may include a laser projector having an optical switch assembly disposed an at input to an optical scanner of the laser projector. The optical switch assembly includes at least one optical switch, and a controller selectively modifies the orientation of each optical switch to selectively change an angle at which laser light is directed onto a scan mirror of the optical scanner. Changing this angle shifts the scan region over which the scan mirror scans the laser light and, relatedly, shifts a region of a field of view of the display. In some embodiments, the controller is configured to modify the optical switch orientation(s) to correct non-idealities in the angle of the laser light.

Abstract: Improved techniques include providing a coupling element on a nose bridge that can overlay left and right images output from respective outcouplers and send the overlay image to a sensor. Based on at least a portion of the overlay image, the sensor may cause the left, right, or both field of views to move until the left and right images are aligned.

Abstract: Systems and methods for controlling an amount of torque transmitted from the temple arm portions to a front frame portion of a frame of a head mounted wearable device are provided. Hinge mechanisms that rotatably couple the temple arm portions to the front frame portion may include torque control devices that provide for torque control in response to rotation and/or deflection of the temple arm portions, to control an amount of torque that is transmitted to the front frame portion. A magnetic torque control device may include first and second arrays of magnets arranged within the hinge mechanism, and that are selectively engaged and disengaged to provide compliance in multiple axes. An elastomer torque control device may include an engagement pin that selectively engages and disengages recesses in an elastomer layer provided within the hinge mechanism to provide compliance in multiple axes.

Abstract: A display system varies a size of a field of view area of a display for augmented reality (AR) applications based on at least one of ambient light in the environment and content displayed at the display and varying a brightness level of the field of view area such that the brightness level within the field of view area is inversely proportional to the field of view area. Based on an amount of ambient light detected in the environment of the display system, the display system adjusts the size of the area of the field of view of the display in inverse proportion to the amount of detected ambient light. As the size of the field of view area decreases, the display system increases the brightness level of the display within the field of view such that the brightness level is approximately inversely proportional to the field of view area.

Abstract: There is provided a wearable heads-up display (WHUD) having a glasses frame, which may comprise a front frame and first and second temple arms each coupled to the front frame. At least a portion of the first temple arm may be foldable relative to the front frame at a first interface disposed at a first distance along the first temple arm away from the front frame. Similarly, at least a portion of the second temple arm may be foldable relative to the front frame at a second interface disposed at a second distance along the second temple arm away from the front frame. The first distance may be different than the second distance. The WHUD may also include a light engine and a display optic both mounted to the glasses frame, and used to form an image viewable by a user of the WHUD.
