Abstract: An optical device includes: a base which includes a main surface; a movable mirror which includes a mirror surface; a first and a second elastic support portions which support the movable mirror so as to be movable along a first direction perpendicular to the main surface; an actuator which moves the movable mirror; and a first optical function portion which is disposed at one side of the movable mirror in a second direction perpendicular to the first direction. The first elastic support portion includes a pair of first levers extending from the movable mirror toward both sides of the first optical function portion in a third direction perpendicular to the first and the second directions. A length of each of first levers in the second direction is larger than the shortest distance between an outer edge of the mirror surface and an edge of the first optical function portion.

Abstract: A virtual and augmented reality system comprising an immersive sound system, sensors, a power source, communications, data processing, and an optical system that delivers photoreceptor density resolution, wide angle, high contrast, binocular vision, continuous depth of field images, is integrated for a fully immersive experience. In one embodiment, an optical system comprises a miniaturized array of projectors geometrically arranged to cover retina photoreceptive areas. Projectors provide full spectrum, amplitude modulated, and controllably divergent beams of light that can be steered with one or more degrees of freedom. Segmented projector arrays greatly improve dynamic performance. An adaptive optics reflector includes an array of fixed, or independently controllable optical elements, that can alter reflected beam properties such that a virtual object may appear to be nearer or further from the viewer. A direct projection, two dimensional array of micro projectors are positioned to deliver a fully immersive image directly into the eye.

Abstract: The present disclosure describes a system and method for coaxial LiDAR scanning. The system includes a first light source configured to provide first light pulses. The system also includes one or more beam steering apparatuses optically coupled to the first light source. Each beam steering apparatus comprises a rotatable concave reflector and a light beam steering device disposed at least partially within the rotatable concave reflector. The combination of the light beam steering device and the rotatable concave reflector, when moving with respect to each other, steers the one or more first light pulses both vertically and horizontally to illuminate an object within a field-of-view; obtain one or more first returning light pulses, the one or more first returning light pulses being generated based on the steered first light pulses illuminating an object within the field-of-view, and redirects the one or more first returning light pulses.

Abstract: A light detection and ranging (LIDAR) system includes a beam collimator, a plurality of first lenses, a plurality of tunable lenses, and one or more optical sources to generate a plurality of optical beams. Each tunable lens may be disposed adjacent a respective one of the plurality of first lenses such that the respective one of the plurality of first lenses is between the tunable lens and the beam collimator. Each of the plurality of optical beams may pass through one of the tunable lenses and one of the first lenses towards the beam collimator. Each of the plurality of tunable lenses may be separately controllable by selectively applying voltage to the tunable lens to adjust a focal length of the tunable lens to compensate for a variation in focus positions of the plurality of first lenses.
