摘要

FIELD: physics. ;SUBSTANCE: device for recording the structure of holographic diffraction gratings forms the first object beam and the reference beam, which falls on the edge of an isosceles triangular prism corresponding to one of the equal sides of an isosceles triangle, and the first object beam falls on the edge of an isosceles triangular prism corresponding to the other of the equal sides of an isosceles triangle. The device forms a second object beam that falls on the face of the triangular prism and refracts to the adjacent face of the triangular prism parallel to the face of the isosceles triangular prism corresponding to the base of the isosceles triangle. The recording material is located between the base of the isosceles triangular prism and the face of the triangular prism parallel to it. The augmented reality display device contains a projection system; a waveguide, on which the input diffraction element and the structure of the holographic diffraction gratings are located.;EFFECT: providing an easy-to-manufacture, compact and lightweight device with a wide field of view and minimal radiation loss.;29 cl, 12 dwg
