Abstract
A system and method for monitoring system including a embedded sensor coupled to an article, wherein the embedded sensor is a direct write embedded sensor using a high temperature light emitting material. A camera system detects illumination signals from the embedded sensors. A processing section processes the illumination signals and determines gas/surface temperatures and strain data for the article.
