Abstract
A projection apparatus for producing a pixel-based illumination pattern has a laser light source for producing coherent laser light and a micromirror array with a multiplicity of mirrors. The mirrors are implemented so as to be controllable in terms of their position, for setting a brightness and/or color of a respective pixel of the pixel-based illumination pattern. The laser light source emits the laser light towards the micromirror array. A beam-shaping element splits the laser light from the laser light source into a multiplicity of partial beams and each of the partial beams is oriented toward one of the mirrors of the micromirror array.
Claims15
A projection apparatus for producing a pixel-based illumination pattern, the projection apparatus comprising:
- a micromirror array having a multiplicity of mirrors, said mirrors being configured for controlling a position thereof for setting a brightness and/or color of a respective pixel of the pixel-based illumination pattern;
- a laser light source for producing coherent laser light and for emitting the laser light towards said micromirror array;
- and
- a beam-shaping element configured to split the laser light from said laser light source into a multiplicity of partial beams, which are each oriented toward one of said mirrors of said micromirror array.
