Abstract:
A system for producing a plurality of light beams on orthogonal and intersecting lines, comprising:a diode laser source providing a laser beam,lens means for collimating the beam, anda plurality of reflective surfaces positioned obliquely in the path of the collimated beam so as to reflect the collimated beam to produce a plurality of substantially orthogonal output beams, said reflective surfaces including two reflective surfaces each oriented substantially at 45.degree. to the beam and in the path of two outer portions of the collimated beam, so as to produce two oppositely directed output beams on essentially the same line, and including third beam means for producing from a middle portion of the collimated beam, a third orthogonal beam on a line which intersects the other two oppositely directed beams and substantially at 90.degree. to the other two beams.
