FIBER-OPTIC PRESSURE SENSOR, VARIANTS AND METHOD FOR PRODUCING A RESILIENT MEMBRANE |
摘要 |
The present invention pertains to the field pressure-measuring techniques using optical systems, and may be used in various technical fields, mainly in medicine. The pressure sensor of the present invention comprises a Fabry-Pérot resonator-interferometer which is arranged at the end of a single-mode fibre light-guide having a Fresnel reflection of 4 %. The mobile mirror of the resonator may consist of a resilient diaphragm attached to the end surface of a capillary. This mirror can also be defined by the end surface of the light-guide section, wherein said light guide is bonded to the centre of a resilient membrane that hermetically seals the air volume within the capillary. The end surfaces of the light guides forming the Fabry-Pérot resonator are arranged within another capillary. The method for producing the sensor involves inserting the section of the light guide into the capillary and feeding a polymerising liquid into said capillary from the side of its end surface, wherein said liquid forms a film that plugs the end surface of the capillary. The end of the light-guide section is inserted into another capillary while defining a gap, wherein said other capillary comprises a single-mode fibre light-guide and is further introduced into the first capillary.
