Optics for VR headsets

Reducing the size of Virtual Reality head-mounted displays while maintaining the optical quality is of main interest to improve the comfort of users. This is a particularly complex design problem due to the very large field of view and high resolution needed to feel the immersion. High compactness with high transmission efficiency and high contrast can be achieved by multichannel optics, whose design for high performance is carried out at LIMBAK introducing intensively freeform optical surfaces, increased resolution via variable magnification, dynamic mapping control and super-sampling via pixel interlacing. This presentation will cover the growing variety of geometries, how to address their challenges and envision their future.
