Filed: 1986-02-27
Abstract: PURPOSE:To measure two directional components of an axis shift from a single image by holding a couple of optical fibers to be connected so that their and surfaces face each other, irradiating the optical fibers with light in a direction perpendicular to the optical fiber axes, and utilizing a light line in a fiber image. CONSTITUTION:One optical fiber 1 is regarded as a standard and then the relative displacement between the optical fibers 1, i.e. axis shift is found. After measurement conditions such as the NA value of a lens 2, the illumination of a lamp, etc., are determined, the width W of the light line or the light intensity of the center part of the light line is measured to know where an observation surface x=xA is and enable the quantity of the (y)-directional axis shift to be measured on the basis of the center position of the light line. Namely, the center position of the light line as to the two optical fibers 1 to be connected is measured and then this quantity is the quantity of the (y)-axial shift of the optical fiber 1. Consequently, two directional axis shift components (x) and (y) are both measured from the single image.
