Abstract
A species of fiber-optic thermometer, employing a gas-sealing movable reflecting element trapping a sealed gas column in a capillary as a temperature-sensitive medium, transfers a proportion of fiber-optic input light to a fiber-optic output as a single-valued function of temperature. This species provides a miniature thermometer exhibiting high temperature sensitivity.
