Viewer with instantaneous enlarged field comprising a mirror and method of manufacturing said mirror

Abstract

Abstract The invention relates to a viewer of the instantaneous enlarged field type having an off-axis holographic mirror (5), which reflects the incident rays ( alpha 2) in a different direction ( alpha 1) in relation to its normal (N). The holographic mirror (5) is in such a position that the instantaneous field (CIH) of the eye (1) of an observer is equal to the total field of a collimated light source reflected on this holographic mirror (5). The holographic mirror (5) may be recorded by means of two coherent monochromatic light sources situated in directions alpha 1 and alpha 2, placed at infinity on either side of the holographic mirror or with two point sources that are not at infinity. <IMAGE>
