TECHNIQUE PRESENTING LIGHT IMAGES AND DEVICE FOR ITS REALIZATION Russian patent published in 2003 - IPC

FIELD: demonstration and advertising aids. SUBSTANCE: usage of this technique in projection facilities presenting images makes it feasible to obtain technical result in the form of increased spectacular and informative presentation of light images emerging in scattered media and recognized at great distances. In compliance with technique light beam act on optically scattering medium by convergence of beams in at least single region of scattering medium. Beams are generated with radiation power less than threshold of visual light sensitivity and summary radiation power in region of beam convergence is carried to value exceeding threshold of visual light sensitivity. EFFECT: increased spectacular and informative presentation of light images. 7 cl, 5 dwg
