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.
Claims17
A method of analyzing a light beam, comprising:
- passing the light beam through an interferometer system;
- wherein said 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 said secondary light beams to a combined beam after exiting said optical arms;
- a light detector for receiving said combined beam and generating a signal indicative of an interference pattern encoded in said combined beam;
- and
- a multipass optical cell positioned at said second optical arm and being configurable to effect a predetermined optical path length within said second arm;
- and
- analyzing an output of said light detector;
- wherein the method further comprises reconfiguring said multipass optical cell to effect a different predetermined optical path length within said second arm, and wherein said analyzing said output comprises combining signals corresponding to different optical path length ranges within said second arm.

A spectrometer system, comprising:
- 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 said secondary light beams to a combined beam after exiting said optical arms;
- wherein said second optical arm is configurable to assume a state selected from a set of states, each state corresponding to a different path length within said second arm;
- and
- wherein said first optical arm is configured to scan, for each state of said second optical arm, an optical path difference between an optical path length of said first arm and an optical path length corresponding to said state of said second optical arm.
