Thermal refractive materials for optical sensor application
摘要
Improved thermooptical sensing devices are provided wherein at various predetermined sectons of an optical fiber is juxtaposed a material characterized by a temperature dependent index of refraction. This material forms a temperature sensitive area which controls the transmission of light through the optical fiber thereby allowing detection of temperature changes along the fiber. The materials may be crystalline thermoplastic polymers, modified organic polymers containing inorganic modifiers, polymer systems containing discrete phases of organic polymers and inorganic additives or thermochromic inorganic compounds.
