Title: Tero Ollikainen: Innovator in Display Technology

Introduction

Tero Ollikainen is a notable inventor based in Salo, Finland. He has made significant contributions to the field of display technology, particularly through his innovative patent related to curved waveguides.

Latest Patents

Ollikainen holds a patent for "Display apparatuses, systems and methods including curved waveguides." This invention encompasses apparatuses and systems that utilize curved optical waveguides. The methods described in the patent include an output-grating of a curved waveguide that features a spatially modulated grating period. This configuration allows for the collimation of corresponding rays of light output from different locations of the output-grating. The adaptive optics of the display engine are designed to compensate for aberrations that vary over the field of view associated with the light corresponding to the image out-coupled by the output-grating. Additionally, the curved portion of the waveguide is engineered to maintain internally reflected light below a critical angle, preventing inadvertent out-coupling. The curved surfaces of the waveguide may also include polynomial surfaces to address lateral color errors and distortion.
