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 centred on the first wavelength and the second filter transmitting the entirety of the spectrum except a second narrow spectral band centred on the second wavelength.
Abstract:
The general field of the invention is that of display systems including an image projector and an associated display screen, said display system being intended for use by an observer situated at a specified location, said display screen having two transparent and substantially parallel faces, and said display screen having on at least one of its transparent faces a plurality of regularly distributed optical patterns. The image projector according to the invention illuminating the screen at a plurality of angles of incidence determined by the position and size of the display screen, and said angles of incidence being centred on an average angle of incidence, the optical patterns have at least one curved reflective surface orientated so as to reflect the light rays having at least the average angle of incidence in one or more directions corresponding to said specified location of the observer. A plurality of embodiments are described.
Abstract:
The general field of the invention is that of helicopter cockpit display systems. The system according to the invention comprises at least a first mobile display screen. Depending on the mission and in order to optimize the vision of the external landscape, the mobile screen or screens are moved so that they are either in the field of vision of the pilot, or out of his field of vision. The symbologies displayed are adapted according to the mission and to the position of the screen.
