Abstract
A new method for measuring the two dimensional modulation transfer function of an image acquisition system containing a CCD array has been described. The results were as predicted by theory. System signal aliasing and feature representation have been discussed. Horizontal cutoff frequencies as low as 40% of the vertical were recorded
