Abstract:
1. Optical telemeter target illumination apparatus comprising at least one light source for target illumination and a collimator collimating the radiation to be emitted by said light source prior to target illumination, said light source being arranged in front of said collimator, said light source comprising at least one laser diode having an emission edge, said emission edge including successive segments, said light source shaving beam forming optics mounted downstream of said at least one laser diode and at least approximately illuminating said collimator, said light source generating offset partial beams, wherein said offset partial beams are emitted from the successive segments of the emission edge of the at least one laser diode, the offset partial beams being parallel to the emission edge in such a way that the offset partial beams substantially overlap, said beam forming optics comprising a first deflection element based on diffraction or refraction of light, and a second deflection element based on diffraction or refraction of light, each of said first and second deflection elements having an essentially plane surface and divided into at least two fields.
