Abstract:
Method and apparatus for aligning objects involve oppositely directed light beams that originate approximately between the objects and are directed toward the objects. Based on a relative position of the light beams to the objects, the objects are moved into a desired position. The oppositely directed light beams can be coaxial, parallel but not coaxial, or transverse.
