Data acquisition devices, systems and method for analyzing strain sensors and monitoring turbine component strain
First Claim
1. A method for analyzing a strain sensor, the method comprising:
- providing a data acquisition device, the data acquisition device comprising an image capture device for receiving and processing light to generate images of the strain sensor, the image capture device comprising a processor;
activating a light source of the data acquisition device for analyzing the strain sensor;
emitting light from the light source through a light tube;
focusing and aiming the light with one or more chamfered portions of the light tube as the light travels through the light tube;
locating, with the processor, a strain sensor portion relative to a background portion within an image of the strain sensor by performing a first analysis of the image;
identifying, with the processor, strain sensor indicia of the strain sensor portion by performing a second analysis of the image; and
conducting, with the processor, a quality analysis of the strain sensor portion by performing a third analysis of the strain sensor portion of the image, the third analysis utilizing a higher bit-depth than the first analysis.

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.
