Paper Abstract

We show that by using a binary spatial filter, and a square law detector, all the defocused OTF's are displayed in a single picture. This unique picture has as horizontal coordinate the spatial frequency, and as vertical coordinate the amount of defocus. The gray level variations of the picture are proportional to the values of the out-of-focus MTF.
