Abstract
A continuous panoramic image seen at infinity from an observation space E is obtained from a prismatic image whose facets consist of alternate and edge-to-edge real images I11, I12, . . . and virtual images I'21, 22, . . . , and by reflection of this prismatic image in a set of sperical concave mirrors MC1, MC2, . . . forming a reflection area. The real images are produced by a first set of image generators M11, M12, . . . The virtual images are the conjugates by reflection in the semi-transparent plane mirrors L1, L2, . . . of images I21, I22, . . . produced by a second set of image generators M21, M22, . . . Amongst other applications, that of ship-control training equipment.
