ASLM Headset Display by Stacked Waveguides
This invention involves beam steering to increase the field of view (FOV) of augmented reality headsets or smart-glasses while maintaining true RGB color with minimal distortion. The invention uses angle-dependent image projection with micro-mirrors operating at 30 hz to create a 90 degree x 30 degree FOV with 1 arcmin/pixel resolution at 24-bit RGB...

Waveguide for Angular Space Light Modulator Display
This invention is a specialized waveguide design that is tuned to the unique Angular Space Light Modulator (ASLM) angle dependent pattern output. This achieves an extended field of view (FOV) output, which is small enough to be integrated into a headset with packaging as small as a typical pair of glasses. This compactness and wide field of view is...

ASLM Multi-Display
This technology is a new method that illuminates digital micromirror device (DMD) with focusing, homogenous illumination with cone angle/numerical aperture/F-number configured to prevent contaminated light to enter incorrect pupils. The technology has one input pupil and multiple diffraction order pupils that produce a multi-display from just one projector. Background: Digital...

MEMS-Based Hybrid Beam Steering for LIDAR
This technology is a LiDAR (light detection and ranging) beam steering system designed to increase scanning range while keeping quality resolution using a microelectromechanically (MEMS) controlled mirror. This allows a single focused beam to be reflected over multiple angles, greatly increasing the possible scanning range. The mirror is specially designed...

Digital Illumination Assisted Gaze Tracking
This invention describes a better design for a wavefront sensor that can capture all the desirable traits of a wavefront sensor in one package. It takes the best attributes of the two most well known wavefront sensors (Shack-Hartmann type and Pyramid type). Alone, these two wavefront sensors can only achieve 1-2 of the three ideal wavefront sensor properties:...

Rotationally Shift Invariant And Multi-Layered Microlens Array
This invention describes a nontraditional use of the Gabor Superlens and is a configuration of multiple microlens array structures. The rotationally shift invariant and multiple microlens array system provides full-field of view imaging wherein all of the incoming light (i.e., light from all directions), in a solid angle of 4pi steradians, is focused...

Rotationally Shift Invariant Optical System
Researchers at the University of Arizona have designed a highly sophisticated LiDAR system that uses a novel optical phased array transmitter in conjunction with a novel spherically shift-invariant (SSI) receiver system to provide depth information over a large 2D scene in a single snapshot. The field of view of the receiver is increased by the novel...

Single-Chip ASLM
This invention is angular and spatial light modulation using a single digital micromirror device. Background: Projection-type spatial light modulators have been hard-pressed to satisfy requirements for head-up and head-mounted displays. Many current technologies also struggle with similar issues for “no-glasses” 3D displays while maintaining...
