<p>The invention relates to the field of image projection with the aid of liquid-crystal screens. …<??>With the invention, the two orthogonal components (P, S) of the light are used to construct the image to be projected, from which there results a significant improvement in the yield. …<??>For this purpose, before passing via a liquid-crystal screen (2), the light is split into two beams (P1, S1) of different directions depending on their polarisations, with the aid of a phase splitter (10), and then after having undergone a modulation of phase by the liquid crystal screen (2), these two beams are recombined in order to construct the image given by the liquid-crystal screen. …<IMAGE>… </p> |
