  • Publication number: 20210311378
    Abstract: The disclosed subject matter relates to a method of projecting an image by means of a light source emitting light pulses and an oscillating micro-electro-mechanical system (MEMS) mirror deflecting the emitted light pulses, comprising: providing a matrix of durations for each pixel, and incrementing or decrementing a pixel index whenever a respective duration indexed by the respective pixel indices in the playout matrix has lapsed; for each light pulse: retrieving the respective intensity and durations indexed by the current pixel indices, calculating an interval from at least one of said durations, emitting said light pulse with said retrieved intensity, and waiting said calculated interval before emitting the next light pulse. The disclosed subject matter further relates to a projector carrying out said method.

  • Patent number: 11016374
    Abstract: The disclosed subject matter relates to an apparatus for projecting a light spot, comprising a light source emitting a light beam having a wavelength and a divergence angle, a mirror arranged in the path of the light beam to deflect said light beam about a nominal deflection angle, the mirror having a surface with a known curvature, and a collimation lens arranged between the light source and the mirror in the path of the light beam, wherein the lens is mounted at a distance z1?f1 from the light source, f1 being the focal length of the lens, and wherein the distance z1 is chosen such that the width of the deflected light beam has a minimum at a pre-determined projection distance.

  • Patent number: 10009600
    Abstract: A light-emitting module for displaying or projecting a video signal comprises at least one mirror mounted so as to be able to oscillate and at least one light-emitting element, which is directed onto the mirror and is controllable via an input, and a computation unit that is connected to the light-emitting element and is configured to output at least one sample value of the video signal, which sample value appears at the input of said computation unit at a first time within a period of the mirror, at its output as a sample value at a second time, which is different from the first, within the same period according to a mapping function that is stored in the computation unit, wherein the computation unit has a control input that can be used to scale and/or offset the stored mapping function. The invention further comprises a display or projection apparatus having a multiplicity of such light-emitting modules, and a method for calibrating the light-emitting module and the apparatus.

  • Patent number: 9810901
    Abstract: The present invention relates to an apparatus for driving and measuring a MEMS mirror system, the MEMS mirror system having a mirror pivotable around an axis by a driving coil and exhibiting a resonance frequency, having a pulse generator and a measuring unit, each electrically connected to the coil. The pulse generator is preferably configured to feed a modulated pulse signal, comprised of pulses separated by intervals and having a modulation frequency different from the resonance frequency, to the coil. The measuring unit is preferably configured to measure a value of a signal output by the coil during an interval of the modulated pulse signal. In a further aspect of the invention a method is provided for driving and measuring the MEMS mirror system.

  • Patent number: 9664357
    Abstract: A device for generating multiple collimated light beams includes a carrier and at least two light generation units mounted on the carrier. The light generation units are configured to emit, each from an aperture, light beams at respectively different wavelengths and being arranged, with respect to axes of the light beams, substantially parallel and substantially in a common plane. A first lens is mounted on the carrier intersectingly to the axes of the light beams and has a principal plane. The light generation units have their apertures aligned along an alignment line substantially perpendicular to the axes of the light beams and the principal plane of the first lens is non-perpendicular to the axes of the light beams and is non-parallel to the alignment line.
