OPTICAL SENSOR WITH CO-LOCATED PRESSURE AND TEMPERATURE SENSORS |
摘要 |
<p>An optical sensor ( 10 ) that provides for concurrent pressure and temperature measurements at substantially the same location includes at least one launch fiber ( 22 ) and at least one temperature sensitive material ( 52 ) having a refractive index that changes with a change in temperature. The launch fiber and temperature sensitive material are spaced from each other across a gap ( 21 ) having length (L). A reflecting fiber ( 26 ) can be provided adjacent the temperature sensitive material. The optical sensor ( 10 ) also includes a sealed cavity ( 20 ). The launch fiber ( 22 ) and reflecting fiber ( 26 ) can be attached to the tube and at least partially disposed within the cavity. Changes in pressure change the length (L) of the gap ( 21 ).</p> |
