Abstract
A method of aligning first and second substantially parallel rod-form elements, such as optical fibers, comprises placing the first element at a position at which it is approximately aligned with the second element and is in the fields of view of two imaging systems that have respective axes that are oblique to each other and to the central axes of the two rod-form elements, and digitizing at least a part of the image of each field of view. The digital data is analyzed to determine location of the first element in each field of view, and relative displacement of the first and second elements is brought about accordingly.
