Abstract
A method for exactly aligning at least two holograms arranged in optical waveguides with respect to one another includes writing a first hologram and a first mark in a first optical waveguide. The method also includes writing a second hologram and a second mark in a second optical waveguide. The method further includes positioning the first optical waveguide and the second optical waveguide with respect to one another. The method also includes illuminating the first mark and the second mark. A pattern occurring during the illumination after passing the first mark and the second mark is detected. The method further includes changing the position of one of the optical waveguides until the detected pattern matches a specified pattern.
