Optical module for near-eye display in augmented realityy
TECHNOLOGY
- Waveguide-based optical system to guide image from side of the head to the eyes
- See-through to allow image super-imposition onto the real world and augmented reality
- Based on reflective optics
- Conceived for integration into smart glasses
- Polychromatic (MTF > 0.3 for 33 l/mm)
APPLICATIONS
- Consumer electronics : Smart glasses to replace smart phones, video games…
- Industry : logistics, assembling chains, storehouses, manufacturing…
- Medicine : guidance for procedures
ADVANTAGES
- Large field-of-view 30°x60° (HV)
- Eyebox 8 x12 mm
- Waveguide thickness 4 mm
- Light-weight and compact for integration into smart glasses (< 20 g)
- Can be tuned to many different out-couplers
- Compatible with OLED micro-displays
- Can be used as monocular or binocular systems
- Customizable (size, source color, form…)
DEVELOPMENT STATUS
- Full simulation with Zemax (Yang J. et al., Opt.Let., 5427 (2016) )
- Tolerance analysis achieved
- Feasibility in glass and plastic under evaluation
- First lab optical device available in 2019
