Abstract
A light diffusing fiber including one or more segments, and a thermochromic coating on at least a portion of the light diffusing fiber. The thermochromic coating is opaque at a first temperature, and is transparent at a second temperature. A system for detecting the temperature of an apparatus including the apparatus, a light diffusing fiber thermally coupled to the apparatus, and a light source optically coupled to the light diffusing fiber. A method for detecting the temperature of an apparatus including thermally coupling a light diffusing fiber to the apparatus, optically coupling a light source to the light diffusing fiber, and monitoring the light diffusing fiber for transmitted light.
Claims20
A light diffusing fiber comprising:
- one or more segments, and
- a thermochromic coating on at least a portion of the light diffusing fiber, wherein
- the thermochromic coating is opaque at a first temperature, and the thermochromic coating is transparent at a second temperature.
A system for detecting a temperature of an apparatus, the system comprising:
- a light diffusing fiber comprising:
- at least two segments;
- and
- a thermochromic coating on at least a portion of the light diffusing fiber,
- wherein the thermochromic coating is opaque at a first temperature, and the thermochromic coating is transparent at a second temperature;
- and
- a light source optically coupled to the light diffusing fiber.
A method for detecting a temperature of an apparatus, the method comprising:
- thermally coupling a light diffusing fiber to the apparatus, the light diffusing fiber comprising:
