Abstract

An interferometer system comprises a light redirecting system for splitting an input light beam into two secondary light beams to respectively propagate along a first optical arm and a second optical arm, and for recombining the secondary light beams after exiting the optical arms. The interferometer system also comprises a multipass optical cell positioned at the second optical arm for effecting a predetermined optical path length within the second arm.
