METHOD AND SYSTEM FOR SIMULTANEOUS RECORDING OF SUPERIMPOSED HOLOGRAPHIC ARRAYS FOR AUGMENTED REALITY DEVICES (VARIANTS) Russian patent published in 2022 - IPC G03H1/04 G02B5/18 

FIELD: computer technology.

SUBSTANCE: invention relates to the field of computer technology for recording superimposed holographic arrays for augmented reality devices. The method includes the following steps: forming the initial radiation beam, directing the initial radiation beam to the interference elimination unit, ensuring the formation of two recording radiation beams by the interference elimination unit, forming two recording channels in the interference elimination unit, illuminating a layer of recording material and one master diffraction optical element /master holographic optical element (master DOE/HOE) containing at least one preformed diffraction/holographic array, at least two non-interfering recording radiation beams indicated, ensuring the simultaneous formation of at least two superimposed holographic arrays from the specified one master DOE/HOE on/in the recording material layer, while the formed superimposed holographic arrays have the same surface period, but a different spatial period. The systems implementing the specified method are also presented.

EFFECT: providing high-quality virtual image output while simplifying the process of recording superimposed holograms in AR devices.
