FIELD: computer diagnostics technology.
SUBSTANCE: method includes forming of radiation of separate partial components of radiation different in physical parameters, directing these components into observation zone, receiving of radiation though focusing element, which radiation is dispersed in observation zone, converting received radiation into respective signals and forming on basis of these of visually discernible image of observation zone. Each separate partial component of radiation is additionally encoded differently from coding of other partial components of radiation and these components are sent to diffuser placed for dispersing radiation falling on it in observation area and dispersing radiation falling on it for lessening its space coherency.
EFFECT: possible detection of masked objects independently of substance of this object.
