METHOD FOR FORMING THREE-DIMENSIONAL MOVING IMAGES WITH LIGHT SCATTERING Russian patent published in 2023 - IPC G02B30/50 H04N13/388 

FIELD: imaging.

SUBSTANCE: invention relates to a method for forming three-dimensional moving images by scattering light. The method includes scanning the surface of an object with two beams of unfocused laser radiation, excitation of metastable states of an impurity that scatter visible light, and registration of radiation from a scattering medium. The excitation of metastable states of the impurity is carried out by absorption of one photon of infrared light in a scattering medium of microparticles of a transparent composite containing erbium ions at the intersection point of two laser beams. As laser sources, at least two different continuous lasers with scanning systems are taken, located near the composite medium, at different angles to it. To form an image profile, a plurality of scattering points of intersection of two laser beams obtained during the scanning process is used.

EFFECT: providing the possibility of obtaining three-dimensional opaque images of the surface of bodies with a high spatial resolution and a scanning speed sufficient to achieve a television shooting mode.
