Hands-on: LetinAR Brings a Larger FOV & Depth of Field to AR with ‘Pinhole Effect’ Optics
LetinAR, a Korea-based startup developing optical solutions for AR headsets and smartglasses, showed off a new implementation of their ‘pin mirror’ optical tech at Mobile World Congress (MWC) this week, bringing a sharp image quality, a large range of focal depth, and a field of view (FOV) that rivals many of the bigger players who instead use waveguide-based optics.
