ABSTRACT:
A beam director for an optical ranging system for measuring relative distance changes between first and second retroreflectors in which a beam of radiation is introduced between the first and second retroreflectors by a steering beam splitter pellicle positioned obliquely therebetween. A portion of the beam is reflected by the pellicle onto the first retroreflector, which reflects it back through the pellicle onto the second retroreflector, which in turn reflects it back onto the pellicle where it interferes with the radiation beam being initially introduced thereon. The pellicle is rotatable about two axes positioned substantially perpendicular to the radiation beam reflected between the first and second retroreflectors and steers the beam to compensate for relative movements of the retroreflectors. The arrangement is such that translation of the pellicle along any of three axes does affect the optical path difference between the retroreflectors.
