Abstract: A pressure sensing film includes first and second films. The first and second films are configured to form an optical cavity therebetween. A flexible transparent film is arranged in the optical cavity. The flexible transparent film is compressible in response to a pressure change in air adjacent the pressure sensing film. A pressure sensing device and a method of sensing pressure adjacent a surface are also disclosed.

Abstract: A remote temperature measurement system for a gas turbine engine includes an optical emitter/receiver in communication with the control system and a probe system embedded within a component of the gas turbine engine, the probe system within a line-of-sight of the optical emitter/receiver, the control system operable to determine a local temperature of the component in response to optical communication with the probe system.
