Device for measuring laser fiber transmission

Abstract

The invention discloses a device for measuring laser optical fiber transmission, which includes a diaphragm, a laser emitting unit provided with an optical fiber joint, and a beam receiving screen for receiving laser light; the diaphragm is detachably located at the front end of the light outlet of the laser emitting unit, and It is used to measure the fiber core diameter. The beam receiving screen is provided with a circular mark with the center of the circle collinear with the axis of the fiber connector. The radius of the circular mark is the radius of the light spot when the laser is incident at the critical angle of the fiber. In the device for measuring laser optical fiber transmission provided by this application, the core diameter of the optical fiber is measured through the diaphragm, and then the corresponding circular mark is obtained, and then the optical fiber is irradiated with laser light, and the image of the optical fiber connector on the beam receiving screen is compared with the circular mark. Mark comparison can quickly know the transmission mode of the laser in the optical fiber, which simplifies the installation and adjustment time of optical fiber coupling, and improves the efficiency of optical fiber coupling installation and adjustment.

Description

technical field [0001] The invention relates to the technical field of laser measurement, in particular to a device for measuring laser optical fiber transmission. Background technique [0002] As a light transmission tool, optical fiber is widely used due to its characteristics of long-distance transmission, low energy loss, flexible transmission and higher safety. Laser processing equipment for optical fiber transmission has been widely used in industry, medical treatment, aviation, etc. Many fields. [0003] In view of the wide range of applications of optical fibers, under the dual market demands of mass industrialization and high coupling efficiency, higher installation and adjustment requirements are put forward for operators. At present, in the optical fiber coupling operation, it usually relies on the installation and adjustment experience of professional operators to artificially estimate the transmission effect of the laser in the optical fiber, and then repeatedl...

Problems solved by technology

At present, in the optical fiber coupling operation, it usually relies on the installation and adjustment experience of professional operators to artificially estimate the transmission effect of the laser in the optical fiber, and then repeatedly measures the spot size of the fiber through CCD and other measuring equipment until it meets the requirements. There is no such thing in the traditional process. Relatively standardized installation and adjustment standards, the operation process is complicated, resulting in low efficiency of fiber coupling installation and adjustment
