Abstract:
1. A method for axially aligning first and second coupling members in a rotatable assembly, comprising: placing the rotatable assembly in a first orientation; directing a first signal portion from a signaling arrangement towards the second coupling member such that the first signal portion is being reflected from the second coupling member; capturing a first image with an image capturing arrangement, the first image including at least a portion of the second coupling member and the reflected first signal portion; placing the rotatable assembly in a second orientation; directing a second signal portion from the signaling arrangement towards the second coupling member such that the second signal portion is being reflected from the second coupling member; capturing a second image with the image capturing arrangement, the second image including at least a portion of the second coupling member and the reflected second signal portion; generating a data set indicative of the relative position of the first and second coupling members based on at least the first and second images; and determining an axial offset between the first and second coupling members based on a determined difference in said generated data.
