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 cut-off frequencies as low as 40\% of the vertical were recorded.

Key Terms: Transfer function, CCD Camera, Image sampling.
