ABSTRACT:
An optical apparatus for correcting deviations from straightness of an array of laser emitters in generally aligned positions along an array direction includes a corrector for aligning the light beam paths in a cross-array direction. A lenslet array shaping optics is provided to direct the light of individual emitters to individual associated regions of the corrector. The corrector may include (1) an array of plane parallel plates individually tiltable to displace the beam by an amount to align the light beam paths in a cross-array direction, (2) a semicylindrical-shaped tray adapted to receive the plane parallel plates such that the plates may be positioned at various angular orientations relative to the light beam path, (3) an array of mirrors associated with a respective one of the beams at an angle to reflect the beam along a folded beam path, (4) an array of lenslets movable in the cross-array direction in the path of an associated beam so as to displace the associated beam by an amount to align the beam paths in a cross-array, or (5) a small diameter rod lens parallel to the array direction and forcibly distorted in the cross-array direction in the path of the associated beam so as to displace the associated beam by an amount to align the beam paths in a cross-array direction.
