  • Temperature sensing system using a phosphor having a temperature-dependent luminescent decay time
    Patent number: 4776827
    Abstract: A temperature sensing and measuring system in which a luminescent material is excited using a light source. The luminescence emitted decays with time, the decay time being dependent on temperature. Thus by monitoring the excitation and luminescence transmitted to and from the material via an optical fibre, the decay time constant and thus the temperature can be determined.
