Inspecting device for end surface of optical fiber

Abstract

Abstract PURPOSE:To perform precise inspection by providing a signal processing part which detects the radiation distribution of light emitted by a light emitting element and reflected by an optical fiber end surface by using a photodetecting element and judges the treatment state of the end surface. CONSTITUTION:An optical fiber 1 is fixed with an optical fiber holder 6 at right angles to the light emitting element 2 and photodetecting element 4. The light emitting element 2 is installed at the center part of the photodetecting element, which uses, for example, a sectorial split type photodiode array. A signal from the photodetecting element 4 is transmitted to the signal processing part 8 through a signal line 7. The processing part 8 judges the treatment state of the end surface of the fiber 1. Thus, the treatment state of the optical fiber end surface is judged precisely and the end surface state of the optical fiber which is laid is easily inspected.
