Beschreibung
Zusammenfassung:	The disclosure includes a system that includes a light source, an optical detector, a camera, and a controller. The light source is configured to illuminate a turbine blade of an engine. The optical detector is coupled to a turbine case of the engine. The camera is communicatively coupled to the optical detector and configured to detect an image of the turbine blade at a stationary condition and an image of the turbine blade at a rotational speed and temperature using the optical detector. The controller is configured to determine and output a relative displacement of at least one timing probe from the turbine blade at the rotational speed and temperature based on the image of the turbine blade at the stationary condition and the image of the turbine blade at the rotational speed and temperature. The at least one timing probe is coupled to the turbine case.
