FIELD: physics.
SUBSTANCE: light spot formation on the target is produced with a beam consisting of, at least, two colours, the combination of which gives an impression of a colour corresponding to the target colour in the spot zone. The emission perception reflected from the target is carried out through a filter of one of the combined colours. A portion of the reflected radiation is passed through the filter, emanating primarily from the spot. The combined colours are formed by sources having emission spectra corresponding to the wavelengths of these colours, respectively.
EFFECT: expanding the functionality, providing concealed aiming.
