.~> Including physical deformation or movement of waveguide
DEFINITION
Classification: 385/12
OPTICAL WAVEGUIDE SENSOR:
(under the class definition) Subject matter where-in an optical waveguide, per se, is responsive to an environmental change.
(1) Note. This is a residual subclass for generic optical waveguide sensing elements which are not elsewhere classifiable. See the SEARCH CLASS notes below.
(2) Note. Combinations of an optical waveguide with an external sensing element or sensing elements, per se, that are not optical waveguides, are classified else-where.
SEE OR SEARCH THIS CLASS, SUBCLASS:
94, for optical fiber/nonfiber device connectors which are sealed to exclude the effects of environmental conditions.
128, for coated optical fiber waveguides which may also act as a sensor under certain conditions.
