Geometric distortion and the edge response function as the most important features of a CCD position sensor were measured with wide angle objectives. Three subpixel interpolation approaches are experimentally investigated: an "errorless" interpolation, which makes use of a data base containing the measured distortion and edge response data, a linear interpolation, and a parabolic interpolation as approximations.
