Stereo cinema

The stereo-cinema is a French invention of Emile Reynaud patented in 1907. This is an optical device giving the illusion of a raised movement and working on the principle of optical compensation .

Description

The whole of the apparatus takes again the principle of Praxinoscope but arranged vertically and whose elements are doubled (for the right eye and for the left eye). The vertices of the two prisms of mirrors are opposite and the whole turns on the same axis. The drums and mirrors are inclined to create an interval for integrating an eyepiece for the viewer. Markings on the bands and on the drums make it possible to arrange the bands correctly. Everything is fixed on one foot. A crank makes it possible to carry out the rotation.

There is only one copy of this device kept at the Museum of Arts and Crafts (Communication sector, device designated stereoscopic binocular praxinoscope )
