Lightguide with 2D-Periodic Grating Structures (Diamond-Shaped) Based on Patent by Wave Optics
Time: 2025-05-26 10:51Source: infocrops.comWriter: infocrops

In this picture you see a model of a lightguide / waveguide system that uses 2D-periodic grating structures (diamond-shaped), according to the approach from Patent WO2018/178626 (by Wave Optics LTD).
Most innovative AR & MR devices nowadays are based on lightguide or waveguide systems in combination with microstructures to couple light in and out. VirtualLab Fusion is capable of detailed modeling of such devices by applying our unique physical optics approach, including all effects (e.g. coherence, polarization and diffraction). We demonstrate this capability by modeling a device mentioned in patent WO2018/178626, consisting of complex 1D- and 2D-perodic grating structures.
