A simple and quantitative alignment procedure between solid state cameras

There are many applications that use multiple charge-coupled device (CCD) cameras. Accordingly it is important to ensure alignment between the CCDs. However, a simple and quantitative alignment procedure has not been introduced thus far. For this reason, this paper proposes an alignment procedure that uses a matched filter algorithm. By using the proposed procedure, the six alignment errors which are x, y, z, roll, pitch, and yaw between the two CCDs can be eliminated. Moreover, the procedure can be applied to the alignment of more than two CCDs. It is believed that the proposed alignment procedure is helpful for precise experiments in many applications that use multiple CCDs.
