Dual or multi-modulation display system are disclosed that comprise projector systems with at least one modulator that may employ non-mechanical beam steering modulation. Many embodiments disclosed herein employ a non-mechanical beam steering and/or polarizer to provide for a highlights modulator.

A multi-mirror array including displaceable mirror elements includes a passive electric damping mechanism for damping disturbances of the displacement positions of the mirror elements.

A holographic waveguide LIDAR having a transmitter waveguide coupled to a beam deflector and a receiver waveguide coupled to a detector module. The transmitter waveguide contains an array of grating elements for diffracting a scanned laser beam into a predefined angular ranges. The receiver waveguide contains an array of grating elements for diffracting light reflected from external points within a predefined angular range towards the detector module.

Aspects of the present disclosure relate to haptic feedback systems and methods for use in head-worn computing systems. A head worn computer includes a frame adapted to hold a computer display in front of a user's eye, a processor adapted to present digital content in the computer display and to produce a haptic signal in coordination with the digital content display, and a haptic system including a plurality of haptic segments, wherein each of the haptic segments is individually controlled in coordination with the haptic signal.

A micro-electro-mechanical device, wherein a platform is formed in a top substrate and is configured to turn through a rotation angle. The platform has a slit and faces a cavity. A plurality of integrated photodetectors is formed in a bottom substrate so as to detect the light through the slit and generate signals correlated to the light through the slit. The area of the slit varies with the rotation angle of the platform and causes diffraction, more or less marked as a function of the angle. The difference between the signals of two photodetectors arranged at different positions with respect to the slit yields the angle.

The invention relates to an optical device (1) for enhancing the resolution of an image, comprising: a transparent plate member (10) configured for refracting a light beam (20) passing through the plate member (10), which light beam (20) projects an image comprised of rows and columns of pixels (40), a carrier (50) to which said transparent plate member (10) is rigidly mounted, wherein the carrier (50) is configured to be tilted between a first and a second position about a first axis (A), such that the plate member (10) is tilted between the first and the second position about the first axis (A), whereby said projected image (30) is shifted by a fraction (ΔP) of a pixel, particularly by a half of a pixel, along a first direction (x), and an actuator means (60) that is configured to tilt the carrier (50) and therewith the plate member (10) between the first and the second position about the first axis (A).

Disclosed is a LIDAR apparatus for a vehicle including a light-emitting unit configured to generate and emit laser light, a light-receiving unit configured to receive reflected light based on the laser light, at least one electronic component electrically connected to the light-emitting unit and the light-receiving unit, and a case configured to accommodate the light-emitting unit, the light-receiving unit, and the electronic component therein, wherein the case is formed of a metal material, and is in contact with at least one element included in at least one of the light-emitting unit, the light-receiving unit, or the electronic component.

A beam director for use in 3D printers comprises a first mirror rotating about its longitudinal axis for redirecting a beam onto a second mirror and then onto a work surface, which may result in a beam with a distorted shape. A beam corrector, e.g. a lens or a reflective surface, is used to ensure the beam has the same desired dimensions in the first and second perpendicular direction when striking the work surface.

An optical coherence tomography (OCT) system using partial mirrors is generally described. In an example, the OCT system includes a swept light source. The system further includes an interferometer into which light from the light source is directed and a detector configured to produce an imaging sample signal based on light received from the interferometer. The system also includes a partial mirror disposed over an aperture, wherein the partial mirror is configured to transmit light within a first wavelength range and reflect light within a second wavelength range.

The present invention is directed to a user-operated spotlight system and method for lighting a performer on a stage or performance space; the user-operated spotlight system comprising a screen which displays an image of the stage and a cursor, a screen cursor positioner adapted to be operated to move the cursor on the screen, a processor connected to the screen, and, a plurality of controllable spotlights which are connected to the processor and which plurality of controllable spotlights can be moved by a user moving the cursor on the screen. The advantage of providing such a user-operated spotlight system is that a single user can operate a plurality of spotlights.
