Abstract:
A method of producing a picture of an end region of parallel optical fibers kept together to form a flat optical fiber ribbon or of end regions of several optical fibers having ends placed in parallel to and at each other in a plane, the method comprising the step of imaging the end region or the end regions respectively by a lens system, so that a centre line in a light beam from the end region or the end regions respectively to the lens system forms an oblique angle to a plane extending through the end region or end regions respectively, and the method further comprising the step of capturing the picture in a capturing plane, which is located in an oblique angle in relation to the centre line, this oblique angle being so selected, that the capturing plane is located in an image plane, in which a picture of the end region or the end regions respectively, when being imaged through the lens system, is located, whereby a sharp picture of the imaged end region or end regions is obtained.
