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...

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.

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...

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...

Single-Chip Streak Camera and Illumination System
This invention uses an Angular Spatial Light Modulator (ASLM) in a projection mode, to create a streak camera. With a novel arrangement of illumination and digital micro-mirror devices (DMDs), an "image per angle" system can be created. Angularly sequential images abut one another such that the viewer sees a single continuous image.
