Monolithic light guide optics enabling new user experience for see-through AR glasses

Augmented and Mixed Reality Optical See‐Through Combiners Based on Plastic Optics

“…Optinvent, a French startup, uses a prism array combiner as a waveguide out-coupler to provide monolithic design and manufacturing with an injection molding technique. 11 The company showed monocular 1D pupil expansion optics with side-mounted or top-mounted design. The prism array is half-mirror coated, and a compensation optic is attached to provide a natural see-through experience.…”

Methods of optimizing and evaluating geometrical lightguides with microstructure mirrors for augmented reality displays

“…As shown in Fig. 1(b), a micro-mirror-array (MMA) geometrical lightguide contains an array of microstructure mirrors coated at the top of wedged grooves [20][21][22]. These shallow micromirror grooves are spaced apart by uncoated flat regions through which the light rays from real world scenes, shown in red dashed lines, can propagate through the parallel-plate substrate.…”
