Abstract
A system for determining wear of an article including an optical fiber for transmitting light from a light source. The optical fiber is embedded in the article, and operatively coupled to an interferometric system. The interferometric system is operatively coupled to a processor. The interferometric system provides the processor with information relating to wear of the optical fiber, and the processor determines wear of the article rate of wear and remaining useful life of the article based on the information relating to wear of the optical fiber.
