Abstract
An incoherent optical correlator is developed to contour-map progressive power lenses, and the beam deviations across the aperture of a tested lens can be read by the disfocal shifting of one mask. A modelling of a local area of progressive lens to an extended sphere-cylindric lens is suggested to calculate the optical properties from the measured deviations in the local area. Thus the optical properties across the whole aperture can be achieved.
