摘要

Apparatus (12) to measure blade vibration in a gas turbine engine (8). An illumination source (20) generates a sequence of illumination bursts in a field of view capturing a passing rotating blade (10) of the gas turbine engine. An imager (22) generates image data including a series of images capturing views of the passing rotating blade. The images are exposed in response to respective illumination bursts. A controller (30) is configured to process the series of images to identify one or more vibration modes of the rotating blade.
