The optimal user experience in VR requires a wide field of view (for the sake of “presence” or “immersion” feeling), high-resolution scenes and headsets as small as possible. These goals are best met by free-form optics able to attain good image quality within the required field of view, and folding the light so that displays can be located as close as possible to user’s eyes. This work will discuss different solutions featuring free-forms and/or light folding in their attempt to replace conventional (rotationally symmetric) optics in this field
Juan C. Miñano has been involved in Optics research since 1982, initially in nonimaging optics (Solid State Lighting and Photovoltaics) and later in imaging applications. Since 1997 he has been Professor at the Universidad Politécnica de Madrid. Later he collaborated with LPI as a Senior Scientist. More recently he co-founded the company Limbak. In 2010 he was honored with the SPIE’s Conrady Award and in 2014 was honored with the Fraunhofer Award of the Optical Society of America.
