Abstract

The invention discloses a device and method for manufacturing a micro-nano optical fiber EFPI sensor F-P cavity, which belongs to the technical field of optical fiber sensing. The device consists of a beam expanding collimating and focusing optical path and a production platform. The optical path includes a laser, a beam expanding and collimating mirror, a fine-tuning mechanism, a mirror, and a focusing lens, which are used to expand, collimate and focus a divergent laser beam. It is micron-scale parallel laser beams; the production platform includes a horizontal and vertical rotary table and a linear slide table, which are used to realize integrated production such as diaphragm cutting, diaphragm and capillary fusion, and optical fiber and capillary fusion. In the method, the shaped laser beam is evenly radiated to the surface of the weldment of the fabrication platform, and the optical fiber EFPI sensor is precisely welded and sealed by using the integrated structure of the fabrication platform. The manufacturing process of the invention is integrally integrated and continuous, the operation is simple and convenient, and the solder joints are effectively guaranteed to be uniform. The micron-level cavity length adjustment technology can realize real-time monitoring and automatic feedback functions, and has important application value.

Description

technical field [0001] The invention belongs to the technical field of optical fiber sensing, and in particular relates to a device and method for fabricating an F-P cavity of a micronano optical fiber EFPI sensor. Background technique [0002] With the continuous development of fiber optic communication technology in the field of national defense science and industry, fiber optic sensors have also been widely used. Compared with other sensors, fiber optic sensors have the characteristics of zero electromagnetic interference, and are especially suitable for online monitoring and fault diagnosis of power systems. Optical fiber sensing technology uses quartz glass optical fiber as the light transmission medium, uses the ability of optical signals to sense and detect external change signals, and uses photoelectric conversion technology to process strained optical signals and demodulate external parameter change signals. Optical fiber sensing sensors have been widely used and im...
