Some new results of experimental study of multifrequency χ (2) -dynamic hologram image formation are presented. The main distinguishing feature of our experiments was the use not only of a multifrequency object wave but a multifrequency reference one, too. As a result, we have simultaneously observed at the same wavelength (λ=564 nm) two frequency summing holographic images formed by nonlinear crystal KTP and arranged nearly symmetrically around SHG image (λ=432 nm) both in transverse and longitudinal directions according to the theoretical treatment. These images can be used for noninertial optical channels switching and addressing with change of wavelength and spatial localization of images including the information.
