A monocentric arrangement of optical components providing stereoscopic display of a virtual image, electronically generated, line by line, from an electromechanical grating light modulator (85) and projected, as a real intermediate image, near the focal surface (22) of a curved mirror (24) by means of a scanning ball lens assembly (100). To form each left and right intermediate image component, a separate image generation system (70) comprises a scanning ball lens assembly (100) comprising a spherical lens (46) for wide field of view and a reflective surface (102). A monocentric arrangement of optical components images the left and right scanning ball lens pupil at the corresponding left and right viewing pupil (14) of the observer (12) and essentially provides a single center of curvature for projection components. Use of such a monocentric arrangement with electromechanical grating light modulator (85) as a linear image source and scanning ball lens assemblies (100) provides an exceptionally wide field of view with large viewing pupil (14).
