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.
