FIELD: physics.
SUBSTANCE: system has a first projecting lens, a second projecting lens, a polarising beam splitter and a reflecting element. The polarising beam splitter is capable of transmitting light with a first polarisation state towards the first projecting lens on a first light beam path and reflecting light with a second polarisation state towards a second light beam path. The reflecting element lies on the second light beam path and is capable of reflecting light towards the second projecting lens. The first and second projecting lenses are capable of directing polarisation encoded images onto a projection screen. Said polarisation conversion system is placed between a virtual light source and a projection screen.
EFFECT: high brightness of the obtained image.
