Latest Patents

Pietila's latest patents include "Waveguides with improved intensity distributions" and "Waveguide-based displays with anti-reflective and highly-reflective coating." The first patent describes an apparatus designed to replicate an image from an input-pupil to an output-pupil using an optical waveguide. This apparatus features an input-coupler that couples light into the waveguide and diffracts it in multiple directions. The intermediate components perform both odd-order and even-order pupil expansion, ultimately directing the light to the output-coupler for viewing. The second patent outlines a near-eye or heads-up display system that incorporates optical waveguides with specialized coatings. These coatings are engineered to have low reflectance for specific wavelengths at certain angles, while reflecting light at other angles, enhancing the display's performance.
