Abstract
Negative imaging of an extended source of polychromatic radiation by an opaque screen is described within the framework of geometrical optics. Spatial domain behind the screen is determined where a negative image is observed, as well as the main optical characteristics of such image. Digital post-processing procedure for improving of an optically obtained negative image is introduced and implemented.
