The extra degree of freedom made available by the use of the FRT allows information regarding both translational and tilting motion to be obtained in an efficient manner.66155 bytesapplication/pdfenThis paper was published in OPTICS LETTERS and is made available as an electronic reprint with the permission of OSA.
