DigiLens shows better waveguide technology for augmented reality, to be used in Sony AR glasses
Now DigiLens have shown off a new diffractive optical waveguide technology using nanotechnoloy materials which promise to be larger and much easier and cheaper to manufacture.
DigiLens’ technology can enable “eyeglass-thin” AR heads-up displays for motorcycle helmets, car windshields, VR headsets, aerospace applications such as fighter jets, and AR smartglasses, said Jonathan Waldern, CEO of DigiLens.
Waldern contends that the display performance of etched structures, called surface relief gratings (SRG’s), as used by Microsoft HoloLens, Vuzix (licensed from Nokia Technologies), and Magic Leap (acquired from Molecular Imprints), are all limited to narrow field of view (FOV), due to the inherent physics of SRG grating interaction.
By contrast, DigiLens makes precision diffractive optics by photographically recording (not etching) the nanostructures.
The company’s Switchable Bragg Gratings (SBG’s) allow much wider FOV with higher efficiency, in addition to offering a “printable” manufacturing benefit.
