DEFINITION

Classification: 250/227.17

Causing polarization change in fiber:

(under subclass 227.14) Subject matter in which the condition sensed changes the polarization of the light passing through the fiber due to some parameter affecting the fiber so that light of a different polarization reaches the photodetector than was incident on the fiber.
