Abstract

An optical cell may include a first port coupled to a second port by an optical path. The optical cell may also include a compensator disposed in the optical path. The compensator may be rotatable about an axis. Rotating the compensator about the axis may vary a distance that the optical path passes through the compensator thereby changing the optical path length of the optical path.

First claim

What is claimed is:

1. An optical cell comprising:
a splitter configured to split a light beam into first and second components and direct the first component into a first optical path having a first optical path length and the second component into a second optical path having a second optical path length;
a coupler configured to join the first and second components; and
a first compensator disposed between the splitter and the combiner in the first optical path, the first co…
