▎ 摘　　要

NOVELTY - Gold foil graphene composite diaphragm multi-eigenvalue pickup includes gold foil graphene diaphragm (1), glass support (2) and optical fiber (3). The glass support is a cuboid with a hole at the bottom and a cavity inside. The gold foil graphene diaphragm is mounted on the top of the inner cavity of the glass support, the optical fiber is inserted into the hole at the bottom of the glass support, and the cavity inside the glass support constitutes an F-P resonant cavity (4). The gold foil graphene diaphragms with different eigenvalues are obtained by adjusting the parameters of the gold foil graphene diaphragm. The resonance frequency of the gold foil graphene diaphragm is matched with the characteristic frequency of the target to be identified. USE - Gold foil graphene composite diaphragm multi-eigenvalue pickup. ADVANTAGE - The gold foil graphene composite diaphragm multi-eigenvalue pickup regulate the resonance frequency through the parameters of the graphene, so that the resonance frequency matches the characteristic frequency of the target to be identified. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the gold foil graphene composite diaphragm multi-eigenvalue pickup. 1Gold foil graphene diaphragm 2Glass supporting piece 3Optical fiber 4F-p resonant cavity
