Abstract

A system for optically monitoring a gas turbine engine includes a viewport having an opening disposed within a casing of the gas turbine engine. The opening extends from an interior side of the casing to an exterior side of the casing, and the viewport is configured to receive an image from inside the casing. The system also includes an optical connection positioned outside the casing and optically coupled to the viewport. The optical connection is configured to convey the image from the viewport to a detector array, and the optical connection includes multiple optical fibers fused to one another to form a unitary substantially rigid fiber bundle.
