Abstract
A head-mounted optical apparatus (10) providing pupil imaging with a very wide field of view. The head-mounted optical apparatus (10) employs a monocentric arrangement of optical components providing stereoscopic display of a virtual image, electronically generated and projected as left and right images from curved surfaces (68). For each right and left image, a ball lens assembly (30) is used to project a displayed intermediate image from the curved display surface (68) toward a beamsplitter (16), which directs an intermediate image toward the front focal surface of a curved mirror (24) that collimates the image to form a virtual image. The beamsplitter (16) transmits the virtual image for each eye to the observer.
