Background
The processing quality of the optical fiber end face has great influence on the overall performance of an optical fiber communication system, statistics shows that more than half of loss in a network is caused by non-ideal optical fiber connection, and the optical fiber end face detection has very important effect on communication and data application. In practice, the end face of the optical fiber is complicated by factors such as non-ideal polishing, scratches, surface or edge chipping, and the like, and the optical fiber cannot be used normally. Therefore, for square capillary fibers, fiber end face angle measurement is essential. Among the prior art, to the terminal surface angle measurement of square capillary optic fibre, the angle measurement system that commonly uses includes a laser source and a target, the target is the location target that sets up at the vertical direction, enlarge certain multiplying power with the fiber end face, observe the fiber end face condition, the target can only be located a direction of laser source, but the specification of square capillary optic fibre is more little, hardly its angular direction of naked eye discernment when the terminal surface angle measurement, need make a round trip to reverse the little square capillary optic fibre and confirm the angle face, make the fiber end face reflect to the target on, so just so greatly reduced terminal surface angle measurement efficiency.
SUMMERY OF THE UTILITY MODEL
