INTERFEROMETER WITH VARIABLE OPTICAL PATH LENGTH REFERENCE MIRROR AND APPLICATIONS THEREOF

الوصف

An interferometer includes a variable optical path length reference mirror to produce a final interferogram from a combination of interferograms. Each of the interferograms is generated at a different optical path length of the reference mirror.

النواحي

The present invention relates in general to interferometers, and in particular, to interferometer architectures, fabrications, and applications. Interferometers split a beam of light into two paths (or arms), bouncing them back and recombining them to detect an interference pattern produced as a result of the recombination. The different arms may be of different lengths or composed of a different material to create alternating interference fringes on a back detector. One of the most significant interferometer-based imaging techniques developed in the past several decades is Optical Coherence Tomography (OCT).
