MULTI-PARAMETER OPTICAL SENSOR AND METHOD FOR OPTICAL SENSOR MANUFACTURING |
摘要 |
A dual-parameter optical sensor having: a fiber optic cable; a fiber Bragg grating (FBG) section provided on the fiber optic cable; and a sleeve affixed to the fiber optic cable such that the sleeve encloses a predetermined portion of the FBG section, wherein the sleeve has a different thermal expansion co-efficient than the fiber optic cable. A method for manufacturing the dual-parameter optical sensor including selecting a fiber optic cable having a predetermined thermal expansion coefficient; forming a fiber Bragg grating (FBG) section on the fiber optic cable; selecting a sleeve having a predetermined thermal expansion co-efficient that is different from the thermal expansion co-efficient of the fiber optical cable; selecting a predetermined portion of the FBG section to be enclosed by the sleeve; and joining the fiber optic cable to the sleeve such that the sleeve encloses the selected predetermined portion of the FBG section. |
