Optical fiber diameter measuring device

The invention discloses an optical fiber diameter measuring device, and the device comprises a carrying platform which is provided with a base platform and a first displacement platform; the second displacement table is arranged on the base table; the optical fiber fixing device is located on the second displacement table, and at least one to-be-measured optical fiber is fixed on the optical fiber fixing device; the image processing device is connected with the image acquisition device, and the image acquisition device is located on the first displacement table and used for acquiring a morphology image of the at least one to-be-measured optical fiber and outputting the morphology image to the image processing device, so that the image processing device determines the diameter of the at least one to-be-measured optical fiber according to the morphology image. Non-contact measurement of the diameter of the optical fiber is achieved through the image acquisition device and the image processing device, it is guar
