Improvement of the Impulse Response of a Deigmaidolon Optical System

This work is devoted to the deigmaidolon effect, which is the spontaneous formation of multiple images of a single object due to the sampling of the object far-field Fourier spectrum. A way of improving the impulse response of the deigmaidolon coherent optical system is presented, based on the illumination of the object by a spherical converging beam of coherent light. The experiment is devoted to the verification of the theoretical results.
