Abstract

In the application of transfer function theory to the process of image formation, one must necessarily be concerned with complex functions. Even in the case of noncoherent image formation (the formation of the image of a noncoherent object), where the object, the image, and the spread function are all purely real, the Fourier transforms of these functions are generally complex. Only in the rather exceptional case where both the object and the spread function are real and even does the situation reduce to one involving only real functions.
