Abstract
The field of the invention is that of viewing systems comprising means for generating stereoscopic images, a viewing device comprising a projector and a semitransparent screen and a pair of stereoscopic glasses. The projector according to the invention comprises means arranged so as to project alternatively a first image emitted at a first wavelength and a second image emitted at a second wavelength different from the first wavelength. The pair of glasses comprises a first filter and a second filter, the first filter transmitting the entirety of the spectrum except a first narrow spectral band centered on the first wavelength and the second filter transmitting the entirety of the spectrum except a second narrow spectral band centered on the second wavelength.
