▎ 摘　　要

NOVELTY - Manufacture of oxidation graphene corrugated film optical fiber F-P sound pressure sensor, comprises (i) preparing and aligning the oxidized graphene corugated film, (ii) removing the coating layer of the single-mode optical fiber, (iii) cutting the end face of the optical fiber to be flat, and wiping, and cleaning, (iv) determining the field-programmable gate array interference distance, (v) inserting the core (8) into the cylindrical counter bore (4) and ensuring that the end surface of the inserting core and the bottom surface contact the cylinder (4), (vi) forming a back cavity (3), (vii) inserting S3-2-type optical fiber (7) from the tail end of the insertion core, and (viii) using spectrograph to observe and determine the field programmable gate Array interference length. USE - Method for manufacturing oxidation graphene corrugated film optical fiber F-P acoustic pressure sensor used in field of emergency rescue, industrial production and human health monitoring. ADVANTAGE - The preparation method is simple, high transfer success rate, and after the transfer of the suspension oxidation graphene the surface is stable. The film surface ripple width, depth and number of the oxidized graphene can be designed according to the requirement, to adjust the sensitive film surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the oxidation graphene corrugated optical fibre F-P acoustic pressure sensor prepared by the preparation method. DESCRIPTION OF DRAWING(S) - The drawing manufacturing the oxidation graphene the corrugated film optical fiber F-P sound pressure sensor schematic diagram. 1Shell 2End face counter bore 6Graphene corrugated film 7Single-mode optical fibre 8Plug core
