<p>A stereogram of superposed images is obtained at the time of photographing by directing the light received from the two axes of observation (1, 2), onto a common optical axis (3). This is done by a means of discrimination of the two superposed images using a semi-reflecting surface (6) and double polarisation filters (5, 7). The semi-reflecting surface acts as a separator of the light from each of the viewing axes (1, 2). The mirror reflect the light beams to project them onto the common axis (3).</p> |
