A rear projection display which uses a polarization sensitive beam splitter (105) to fold the rear projection optical path. The folded light path facilitates a compact design which can be tiled vertically and horizontally. An image source produces an image having a polarization which is transmitted through the beam splitter (105). Light passing through the beam splitter is incident on a polarization state converter (107) which converts the polarization state of the image to one which is reflected by the polarization sensitive beam splitter. The converted image is reflected by the polarization sensitive beam splitter (105) towards a screen (109). The image can be transmitted through the screen (109) for viewing.

La présente invention concerne un afficheur à projection par transparence qui utilise un diviseur de faisceaux sensible à la polarisation (105) pour le renvoi du trajet optique de la projection par transparence. Le renvoi du trajet optique favorise la mise an point d'un modèle compact permettant des juxtapositions verticales et horizontales. Une source d'image produit une image présentant une polarisation qui traverse le diviseur de faisceaux (105). La lumière traversant le diviseur de faisceaux arrive en incidence sur un convertisseur d'état de polarisation (107) qui convertit l'état de polarisation de l'image en un état de polarisation renvoyé vers l'écran (109) par le diviseur de faisceaux sensible à la polarisation (105). L'image à présenter peut être transmise au travers de l'écran (109).
