Abstract:
1. An optoelectronic device for projecting a first beam of coherent first electromagnetic radiation onto a surface and a second beam of coherent second electromagnetic radiation onto the surface, comprising: a first radiation source adapted for emitting the first beam of coherent first electromagnetic radiation; a first phase-modifying element in a beam path of the first electromagnetic radiation for modifying a phase of the first electromagnetic radiation in a subzone of the first beam; a radiation-directing element in the beam path of the first electromagnetic radiation for changing a beam direction of the first beam; a second radiation source adapted to emit a second beam of coherent second electromagnetic radiation; an optical combiner adapted to superimpose the first beam on the second beam; and a second phase-modifying element in the beam path of the second electromagnetic radiation for changing a phase of the second electromagnetic radiation in a subzone of the second beam.
