METHOD FOR FORMING A HOLOGRAM CONTAINING NON-VISUALIZED PHYSIOLOGICALLY IMPORTANT INFORMATION Russian patent published in 2004 - IPC

FIELD: holography.

SUBSTANCE: method includes separation of laser beam by means of light-dividing cube on support and object branches, direction of support branch of beam onto lens expander, forming a spherical wave front, lighting of object by received light beam, which object is placed in such a way, that light beam deflected from it surface falls along normal line with deviation of no less than 35° on same side of photo-plate, receiving a hologram by development, fixing and drying with whitening of photo-plate, receiving reflective hologram by recording a hologram from photo-plate containing source hologram and used as hologram object, onto second photo-plate, not containing a hologram, while second photo-plate is placed in plane of focusing of copied actual holographic image, lighted on opposite side by non-modulated spherical wave front received on basis of support branch of laser beam at 45° angle, and processed according to method said above with no whitening. When recording source hologram method includes use of carrier of non-visualized physiologically important information as hologram object, being in state of active or passive information transfer, and/or as light beam diffuser placed in place of output from lens expander of spherical wave front received on basis of subject branch of laser beam.

EFFECT: higher efficiency.
