ABSTRACT:
This disclosure describes an optical system which serves to multiply the change in the path length of an optical system. The system employs an even number of pairs of mirrors which are displaceable along a line or lines parallel to an axis. Each segment of the optical path is between mirrors which are oppositely displaceable, so that the length of each segment is increased by an amount equal to twice the displacement of the mirror pairs.
