▎ 摘　　要

NOVELTY - The method involves selecting a single layer or layers of a copper graphene film. The film comprises a chemical vapor deposition (CVD) single layer. A tail end of a single-mode optical fiber is fixed to an optical fiber cutting knife. Fabry-Perot interference is determined to form an optical fiber-air-graphene film interference cavity. Fabry-Perot interference cavity long detect device building process is perfroemd. Graphene film Fabry-Perot optical fiber sound pressure signal sensor manufacturing process is performed according cavity length change rule to receive a sound pressure signal. USE - Method for manufacturing a graphene film Fabry-Perot optical fiber sound pressure signal sensor in underwater electroacoustic, medical and biomedical engineering fields. ADVANTAGE - The method enables realizing graphene film Fabry-Perot optical fiber sound pressure signal sensor manufacturing process in a simple manner with less volume and better anti-electromagnetic interference effect. The method enables limiting a membrane due to reduction of sensor thickness so as to improve sensitivity of a sound pressure signal sensor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for manufacturing a graphene film Fabry-Perot optical fiber sound pressure signal sensor in underwater electroacoustic, medical and biomedical engineering fields. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for manufacturing a graphene film Fabry-Perot optical fiber sound pressure signal sensor in underwater electroacoustic, medical and biomedical engineering fields.'(Drawing includes non-English language text)'
