Abstract
An apparatus and method for characterizing light beam collimation and alignment. A liquid crystal device receiving a light beam from a collimation lens has a lenslet array generated thereon. A corresponding array of point spread functions are detected by a charge coupled device camera, from which light beam collimation and alignment are characterized. The data may be further used to adjust the collimation lens to correct misalignment.
