Abstract: An optical probe for a gas turbine engine includes a housing. Also included is a plurality of optical fibers, a portion of each of the optical fibers secured to fiber holders. Further included is an optical head disposed within the housing and having channels extending in a longitudinal direction of the optical head, the fiber holders disposed within the channels. Yet further included is a cap disposed within the housing and operatively coupled to the optical head, the plurality of optical fibers extending through the cap. Also included is an inner tube operatively coupled to the cap, the plurality of fibers extending through the inner tube.
