  • Patent number: 11940619
    Abstract: A mirror device including a micromirror, which is excitable to an oscillatory motion such that a first impingement angle of a beam of light impinging upon its reflective surface varies within a first value range, and a cover element, which is stationary so that, due to the reflection at the reflective surface, the beam impinges upon at least one inner surface of the cover element and partially impinges as reflection beam upon the reflective surface. The cover element is aligned at an incline relative to a neutral position of the micromirror such that a second impingement angle of the reflection beam impinging upon the micromirror lies within a second value range outside the first value range. The reflective surface has a coating, which has a reflection coefficient of at least 0.6 for the first value range and a reflection coefficient of maximally 0.4 for the second value range.

  • Patent number: 11650151
    Abstract: Light is projected through a grid (e.g., a Ronchi ruling) and onto a background, where it forms an image of the ruling. The light from this projected image is then reflected back onto the same grid, with a polarizing refractor (e.g., a Rochon polarizing prism) imparting a small offset between the projected and reflected light, and then on to an imaging camera. Thus, a separate source and cutoff grid is not needed, resulting in a focusing schlieren system that is compact and easy to construct and align. In some embodiments, translation of the polarizing refractor along the instrument axis provides a sensitivity adjustment of the resulting schlieren images. Manipulation of the polarization state of the light through the system allows the projected and reflected light to be coincident, maintaining a small footprint for the system, which can be mounted to the front of the imaging camera.

  • Patent number: 11386535
    Abstract: The disclosure provides an image blending method. The method includes projecting a first image and a second image onto a projection surface by a first projector and a second projector, respectively, and the first image and the second image overlap each other; and projecting the first control pattern onto the first image, adjusting the first control pattern such that a first control pattern frame matches a boundary of an overlapping area, and thereby identifying a position of a first non-overlapping area in the first image. Additionally, a similar operation is performed by the second projector to identify a second non-overlapping area in the second image. All pixels in the first non-overlapping area and the second non-overlapping area are adjusted such that the black-level brightness of the first non-overlapping area and the second non-overlapping area correspond to the black-level brightness of the overlapping area to obtain better brightness uniformity.

  • Patent number: 11379946
    Abstract: A projector is provided with a correction information generator and an image information corrector described below. The correction information generator estimates a reference plane having a normal vector that is the cross product of the average of normal vectors in N regions in the result of measurement of the shape of a projection surface and a first vector corresponding to a component having the largest degree of dispersion among the N normal vectors. The correction information generator estimates an imaginary projection surface by causing the result of projection of the projection surface on the reference surface to rise upright with respect to the reference surface and generates image correction information based on the imaginary projection surface. The image information corrector generates correction image information from image information on a projection image and the correction information. The projector projects an image based on the correction image information on the projection surface.

  • Patent number: 11269244
    Abstract: The invention provides a system and method that reduces the precision of the manual alignment process. Users select correspondences between projectors or components of a projector, to form a common coordinate. Using models of the display system, and projectors, the common coordinate system can be mapped quickly to the entire display. The process avoids a need to measure screen points, and allows the user to move significantly fewer points. Alternatively, the invention allows introduction of machine-vision style algorithms into manual calibration techniques to improve performance. This overcomes the tediousness of prior systems by introducing models of the display into the manual alignment process, allowing selection of a small number of points on each projector, and avoiding selection of precisely measured screen points. The system conversely finds correspondences between projectors, allowing mapping of the projectors into a common coordinate system, and quick warping of the coordinate system to the screen.

  • Patent number: 11206380
    Abstract: A projector controller includes an object detector and control electronics, and is configured to protect audience members from intense light imposing an exclusion zone in front of a projector. The object detector is configured to optically sense a presence of an object in a detection region beneath the exclusion zone and above the audience members. The control electronics is configured to control the projector when the object detector indicates the presence of the object in the detection region. A method for protecting audience members from intense light imposing an exclusion zone in front of an output of a projector includes: (i) optically sensing a presence of an object in a detection region between the exclusion zone and the audience members, and (ii) controlling the projector when the presence of the object is sensed in the detection region.
