Information entropy method and the description of echo hologram formation in gaseous media

Abstract

© 2018 Astro Ltd. The effect of collisions with a change in velocity of gas particles, on the value of information entropy, is associated with the spectral structure of the echo hologram's response, where its temporal form is considered. It is shown that collisions with a change in gas particle velocity increase the 'parasitical' information, on the background of which the information contained in the temporary shape of the object laser pulse is lost.
