Abstract
A device for projecting a time variable optical pattern onto an object that is to be measured in three dimensions, the device comprising a frame for an optical pattern; a light source with optional illumination optics; and imaging optics, wherein the optical pattern is on slide that is attached to a movement mechanism that moves the optical pattern relative to the optional illumination optics and/or relative to the imaging optics, wherein the movement mechanism causes a movement of the optical pattern in a slide plane that is oriented orthogonal to an optical axis of the imaging optics.
