Problems solved by technology
[0004] Optical reflectors mainly include optical reflectors and fiber gratings. If the former is a non-fiber reflector, its main problem is that it is difficult to couple with the optical fiber and the cost is high. Reflective film is also difficult to process and high in cost; the main problem of the latter is temperature sensitivity, and the reflection wavelength band of fiber grating is narrow, which limits its application range

Embodiment Construction
[0025] Such as figure 1 The manufacturing method of a kind of optical fiber type light reflection device shown, comprises the following steps:
[0026] Step 1. Cut the ends of the two optical fibers perpendicular to the axis of the optical fiber with an optical fiber cleaver to obtain the end face of the optical fiber;
[0027] Step 2. Place the two optical fibers in the two V-shaped grooves and press and fix them with a pressure plate;
[0028] Step 3, moving at least one of the two V-shaped grooves through mechanical adjustment so that the processed end faces of the two optical fibers are in contact and the fiber cores are aligned with each other;
[0029] Step 4. Melting the end faces of the two optical fibers through the discharge arc at a temperature higher than 1800 degrees Celsius;
[0030] Step 5. Choose one of the two optical fibers and connect the test instrument to the other end of the optical fiber. Use the test instrument to detect whether there is light reflect...

The invention discloses a method for manufacturing an optical fiber type light reflection device. The method comprises the following steps of: 1, treating the end faces of two optical fibers to be similar to mirror surfaces; 2, respectively putting the two optical fibers into two V-shaped slots, and compacting and fixing the two optical fibers by a pressing plate; 3, moving one of the two V-shaped slots by mechanical adjustment to make the treated end faces of the two optical fibers contacted with each other and the fiber cores align each other; 4, melting the end faces of the two optical fibers at high temperature of discharge arc, and connecting the two optical fibers together; and 5, selecting any one of the two optical fibers, connecting a test instrument to the other end of the optical fiber, detecting whether a light reflection phenomenon exists by the test instrument, if the light reflection phenomenon exists, determining the light reflectivity and adding a protective sheath near a joint of the two optical fibers, otherwise, disconnecting the melted point of the two optical fibers, and repeating the steps from one to five. The method is simple, and is low in cost; and the optical fiber type light reflection device is convenient to manufacture, and less influenced by temperature, vibration and other environment factors.
Description
technical field [0001] The invention belongs to the technical field of optical fiber sensing, and in particular relates to a manufacturing method of an optical fiber type light reflection device. 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 modulatio...
