  • Patent number: 10356374
    Abstract: A projection system includes an invisible light projector, an imaging unit, an image generator, and a visible light projector. The invisible light projector projects a predetermined invisible light image onto the object via invisible light. The imaging unit captures an image of the invisible light projected from the invisible light projector. The image generator measures a shape of the object based on the image captured by the imaging unit to generate image data showing image content for projection onto the object in accordance with the measured shape. The visible light projector projects the image content shown by the image data onto the object via visible light. The invisible light projector emits pulsed invisible light to project the measurement pattern. The image generator generates the image data based on an image captured in accordance with a timing for the pulsed light emission.

  • Patent number: 10349019
    Abstract: A projection system includes an invisible light projector, a background member, an imaging unit, an image generator, and a visible light projector. The invisible light projector projects a predetermined invisible light image onto the object via invisible light. The background member is disposed behind the object in a direction of the invisible light emitted from the invisible light projector. The imaging unit captures an image of the invisible light projected from the invisible light projector. The image generator measures a shape of the object based on the image captured by the imaging unit to generate image data showing image content for projection onto the object in accordance with the measured shape. The visible light projector projects the image content shown by the image data onto the object via visible light. The background member has a light shielding surface that does not diffusely reflect the invisible light incident thereon.

  • Patent number: 10349017
    Abstract: An illumination device includes a light source unit and a filter wheel. The filter surface of the filter wheel includes a first surface segment and a second surface segment arranged behind the first surface segment in the direction of rotation. When the filter surface is rotated, the first and second surface segments successively extend into the illumination beam path. The first surface segment transmits only a first part of the spectrum of the emitted light and the second surface segment transmits only a different second part of the emitted light. The control unit controls the light source unit and drives the filter wheel so the light with the different spectra is emitted sequentially in time for a predetermined partial illumination duration. During the partial illumination duration of the emitted light with the first spectrum, the first or second surface segment extends into the illumination beam path.

    Abstract: A MEMS device includes a fixed structure and suspended structure including an internal structure and a first arm and a second arm. Each arm has a first end fixed to the fixed structure and a second end fixed to the internal structure. The ends are angularly arranged at a distance apart. Piezoelectric actuators mounted to the arms are driven so as to cause deformation of the arm and produce a rotation of the internal structure. In a resting condition, each of the first and second arms has a respective elongated portion with a respective concavity. The internal structure extends in part within the concavities of the elongated portions of the first and second arms.
