Paper Abstract

Gabor's theorem concerning the number of degrees of freedom of an image, (space-band-width product), is proven in two different ways. It is indicated in which way this theorem can be generalized for the case of aberrated images, leading to an increase of the number of degrees of freedom in the presence of certain aberrations. A paradox, generated by the calculation of this number in two different ways, leading to different results, is formulated, and its solution indicated.
