ABSTRACT:
The edge of an end face of a fiber image is crossed at least once by at least two measurement windows at different locations. The changes in the intensity values registered for each of the measurement windows are obtained and used for interpretation to obtain the error angle of the end face of the fiber relative to a plane extending perpendicular to the fiber axis.
