Abstract: Data acquisition devices for analyzing reference objects and systems for monitoring turbine component deformation are provided. A data acquisition device has a longitudinal axis and includes a lens assembly and an image capture device in communication with the lens assembly for receiving and processing light from the lens assembly to generate images. The data acquisition device further includes a light source and a light tube coupled at a rear end to the light source. The light tube extends along the longitudinal axis between a front end and the rear end, and is operable to transport light from the light source therethrough and emit the light from the front end. The data acquisition device further includes an actuator operable to activate the image capture device and the light source.

Abstract: Systems and methods for monitoring turbine component deformation are provided. The turbine component has an exterior surface. A method includes directly measuring a strain sensor configured on the exterior surface of the turbine component along an X-axis, a Y-axis and a Z-axis to obtain X-axis data points, Y-axis data points, and Z-axis data points.
