Abstract
A method and system are provided for the constant path-length translation of a laser beam. At least one pair of mirrors disposed at an angle (e.g., 90.degree.) to one another and fixed in relation to one another are disposed in the path of the (incoming) laser beam. The mirrors are positioned such that the incoming laser beam impinges on the first mirror, is reflected to the second mirror, and iii) is reflected from the second mirror as an (outgoing) laser beam parallel to the incoming laser beam. A positioner is coupled to the mirrors for simultaneously moving them in a direction that is parallel to the target plane and in a plane defined by the incoming and outgoing laser beams.
