Widefield : Optical module for near-eye display in augmented reality

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

Under Development

Ongoing Conectus investment for proof of concept – 300 k€

Planned project end date:  May 2019
