OPTICAL PRESSURE SENSOR |
| 摘要 |
An optical pressure sensor is disclosed having a pressure sensing optical cavity. A temperature sensing optical cavity at the sensor head is used by an interrogator to correct a pressure signal for effects of temperature. The optical cavities may be, for example, Fabry Perot cavities in the sensor head. |

1. An optical pressure sensor comprising:
a sensor head comprising a pressure sensing optical cavity and at least one temperature sensing optical cavity; and an interrogator optically coupled to the sensor head, and arranged to generate at least one signal representing pressure at the sensor head responsive to the pressure sensing optical cavity, the at least one signal representing pressure being temperature corrected by the interrogator responsive to the at least one temperature sensing optical cavity. |
