Abstract
PURPOSE:To reduce the size of a device and to shorten its inspection time by observing a transmitted light image formed with illumination light reflected by a reflecting mirror after passing through bare optical fibers and a transmitted light image with illumination light passing through bare optical fibers. CONSTITUTION:The reflecting mirror 1 is installed in one of the normal directions of the bare optical fibers f1-f5 led out of a multicore optical fiber F, and while illumination light l1 is projected on the bare optical fibers f1-f5 from the other normal direction, illumination light l2 is projected on the bare optical fibers f1-f5 from the different direction from the normal direction to perform inspection by observing the transmitted light image Y formed with the illumination light l1 reflected by the reflecting mirror 1 after passing through the bare optical fibers f1-f5 and the transmitted light image X formed with the illumination light l2 passing through the bare optical fibers f1-f5. In this constitution, the optical axes of the transmitted light images X and Y on the reception side become parallel, the two images are picked up closely, and the required moving distance of an image pickup device system is reduced.
