Abstract: A two-dimensional exit pupil expansion method for waveguide display based on polarization volume gratings (PVGs) is provided. Based on the polarized diffraction properties of the PVGs as waveguide coupling elements, a light beam from a microimage source system is introduced into and then propagates in a waveguide medium. By a composite PVG structure, a light field of a transmitted image is subjected to two-dimensional exit pupil expansion and emission, and finally incident into human eyes to achieve waveguide augmented reality imaging.

Abstract: A magnetic-inductance component is a multi-turn closed coil connected head to tail and wound around a magnetic circuit. A magnetic-inductance value of the magnetic-inductance component is adjusted by selecting metal conductors with different numbers of turns, materials, cross-sectional areas, and lengths to change an amplitude and phase of a magnetic flux of the magnetic circuit. The present invention changes the operating state and operating trajectory of a vector in the magnetic circuit by adding the magnetic-inductance component to the magnetic circuit or removing the magnetic-inductance component from the magnetic circuit, to make a state of a magnetic flux vector in the magnetic circuit to be consistent with a target magnetic flux vector state. A magnetic circuit vector model built by using the magnetic-inductance component as a core is more consistent with the actual physical situation, which is beneficial to the improvement of the accuracy of magnetic circuit analysis and calculation.
