Abstract
In this paper we demonstrate that the light diffracted by a simple compact disc can be used to generate photographic images of a certain kind. Being the compact disc an axicon that generates a diffraction-free beam, we show that the focusing position of an image depends of the wavelength of the diffracted light, what makes possible its use as a spectral filter.
