METHOD OF CREATING HOLOGRAPHIC IMAGES OF DRAWING Russian patent published in 2010 - IPC G03H1/00 

FIELD: physics.

SUBSTANCE: image of the initial drawing is converted into a digital raster image. The diffraction pattern on each point of the future hologram is calculated, where the said diffraction pattern is created from all emitter elements of the digital raster image. The interference pattern obtained from interaction of the calculated diffraction pattern with the calculated wave front from a virtual reference point- or extended radiation source, which is identical to the real wave front of the source, which will be used in making the holographic image of the drawing is calculated. The result is used as a signal for modulating the radiation beam which forms the diffraction structure of the hologram on a carrier. The hologram is created in form of a set of discrete elements distinguished by their optical properties.

EFFECT: obtaining an image with good technological parametres, including less geometric deviation of the obtained image from given geometry, higher contrast of the obtained image and low level of noise in illuminated and non-illuminated areas of the image.
