Abstract: A method of obtaining multizone images of objects by the steps of converting the image of an object into an image of its spatial-frequency spectrum conveying information on spatial structure of the object and separating in the spectrum at least one zone whose radiant flux is integrated in real-time to produce video signals of the respective object image. Arranged successively in a multizone system ahead of a spectrum separator means are a spatial-time modulator and an optical means for converting the image of the object into the image of the spatial-frequency spectrum.
