Abstract
A fiber-optic temperature-measuring apparatus which monitors the photo-luminescence of a body of solid material subjected to the temperature to be measured. Exciting radiation is conducted by means of at least one optical fiber towards a material with temperature-dependent luminescence which is in optical contact with the fiber, whereby luminescence occurs. The radiation emitted as a consequence of the luminescence is transmitted via at least one optical fiber from the body to a place of measurement, where a measure of the temperature may be obtained. The luminescent body may consist of a semiconductor material.
