| 20120029864 | Photoluminescent Temperature Sensor Utilizing Singular Element for Excitation and Photodetection - 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. | 02-02-2012 |
