  • Photoluminescent temperature sensor utilizing singular element for excitation and photodetection
    Patent number: 8751188
    Abstract: A photoluminescent temperature sensing device and method utilizing a semi-conductor optical device adapted to operate as both a light-emitting device and a light detection device. The optical device emits a pulse of incident light, producing photoluminescent light that is received at the optical device. Signal information associated with a temperature-dependent characteristic of the photoluminescent light is created and temperature information if obtained from the signal information.
    Type: Grant
