Abstract:
1. A method for measuring a rotational and positional offset between a first imaging device and a second imaging device, the method comprising: obtaining an image of a fixture with the first and second imaging device, wherein the first imaging device comprises a Hartmann-Shack camera; superimposing a marker in a nominal position over the images of the fixture taken with the first and second imaging device; moving the marker from the nominal position in the image obtained with the first imaging device to a position that is substantially aligned with the images of the fixture; moving the marker from the nominal position in the image obtained with the second imaging device to a position that is substantially aligned wit the images of the fixture; and comparing movement information of the marker in the first image with movement information of the marker in the second image to determine the rotational and positional offset between the first and second imaging devices.
