In this paper, we provide an overview of the basic principles of our light field display and demonstrate its advantages over traditional AR displays for close-range applications such as endoscopic ultrasound probe localization, AR-guided gallbladder drainage, and medical training upper endoscopy. In addition, we describe an optical approach to address the inherent spatial-angular tradeoff of light field displays.enfalseconference paper2-s2.0-105003739397
