Abstract
A crystalline structure, comprising an optical waveguiding region, a crystalline fluorescent temperature sensing region, and a crystalline junction between the optical waveguiding region and the crystalline fluorescent temperature sensing region. An embodiment of the present invention is a novel fiber-optic temperature sensor functional under high-temperature conditions. The fiber-optic temperature sensor comprises a continuous crystalline fiber optic high temperature sensor probe having a crystalline optical waveguiding region with first and second ends, and a crystalline fluorescent temperature sensing tip at one end thereof. The crystalline optical waveguiding region and the crystalline fluorescent temperature sensing tip are preferably crystallographically and thermomechanically compatible with each other. The fluorescent temperature sensing tip contains fluorescent ions that can be excited to fluoresce and produce a fluorescence emission. The fiber optic high temperature sensor probe also contains a crystalline junction preferably having a continuous, crystalline structure throughout. The crystalline junction is located between, and attached to, the crystalline fluorescent tem…
