Definitions

  • the light segments of a segment light distribution are symmetrical with respect to the V-V axis in the light image.
  • the light segments of a segment light distribution of half of a line are mirrored about the axis V-V.
  • straight lines G1 and G2 differ from one another only in the case of shifted segment light distributions. If the projection modules 10, 20 were aligned identically, the straight lines G1, G2 would coincide.
