Abstract: A light projection system for projecting full-resolution, high quality images into different directions. The system includes a light source configured to provide a homogenous output beam of light and an illumination shaping optic elements configured with at least one of a predetermined cone angle, numerical aperture, and F-number. The system also includes a spatially-dependent, angular light modulator (ALM) with a plurality of pixels, each having an ON state, an OFF state, one input pupil, and N diffraction order pupils.

Abstract: A rotationally shift invariant and multi-layered array system for full-field of view and/or photon collection by 4pi steradian field of view. In the system, all of the incoming light (i.e., light from all directions), in a solid angle of 4pi steradians, is focused inside the optics. The optics have a spherically shift invariant structure, providing rotational shift invariance. The system comprises a nontraditional use of the Gabor Superlen and is a configuration of multiple microlens array shell structures with concentrically arranged bulk optical components. Examples of such bulk optical components include Luneburg lenses, micro-structured surfaces, a single lens, a plurality of single lenses, ball lenses, metalenses, diffractive optical elements, and magnetic lenses. In an embodiment, the Gabor Superlens (i.e., microlens array) is planar. In an embodiment, no moving parts are required for the system to achieve truly full-field of view imaging and/or photon collection by 4pi steradian field of view.

Abstract: A LiDAR system that uses a MEMS-based scanning mirror that reflects pulsed light generated by a laser. The scanning mirror reflects the light through a lens system which collimates the light and allows its transmission to a digital micromirror device that steers the light to different locations corresponding to different orders towards an object to be detected. A photodiode, operational amplifier, timing chip and processing device then receive and process the light signal and generate a control sequence to synchronize timing of movement of the MEMS-based scanning mirror and the digital micro mirror device.
