Abstract

The invention discloses an optical fiber type light reflection device, which comprises an optical fiber, wherein an optical fiber wrapping layer is arranged on a fiber core of the optical fiber; a coating layer is arranged on the optical fiber wrapping layer; and micro bubbles capable of performing fresnel reflection on a light signal emitted into the optical fiber are contained in the fiber core of the optical fiber or a micro space close to the optical fiber wrapping layer of the fiber core. The invention also discloses a method for manufacturing the optical fiber type light reflection device. The optical fiber type light reflection device is coupled with the optical fiber conveniently, has low cost and a small volume, and is less influenced by temperature, vibration and other environment factors; and the manufacturing method is simple, and is convenient for batch production.

Description

technical field [0001] The invention belongs to the technical field of optical fiber sensing, and in particular relates to an optical fiber type light reflection device and a manufacturing method thereof. Background technique [0002] Optical fiber sensing technology is an emerging technology gradually formed with the development of optical fiber communication. Because it is an optical sensor, it has many advantages such as high sensitivity, anti-electromagnetic interference, and easy construction of multiplexing and distributed measurement systems, and has attracted widespread attention. [0003] There are four main types of modulation methods for optical fiber sensors: optical intensity modulation, optical phase modulation, optical wavelength modulation, and optical polarization modulation. Compared with other optical fiber sensors, the optical intensity modulation type has the advantages of simple structure, reliable operation and low cost. However, the light intensity ...
