ABSTRACT:
In a projection arrangement comprising a light source (1) for generating a luminous field (2), a reflecting light modulator (4; 27) onto which light coming from the luminous field (2) may be directed, said light being modulated by the light modulator (4; 27) in order to generate an image, and further comprising projection optics (5; 21, 32), arranged following the light modulator, for projecting said image, the projection optics (5; 21, 32) comprise imaging optics (5; 21) including a mirror (9, 25) and a lens (6; 7; 8; 22; 23; 24) arranged between the light modulator (4; 27) and the mirror (9; 25), the light coming from the light modulator (4; 27) and reflected by the mirror (9; 25) passing twice through the lens (6; 7; 8; 22; 23; 24) and the light coming from the luminous field (2), which is directed onto the light modulator (4; 27), passing through the lens (6; 7; 8; 22; 23, 24) of the imaging optics (5; 21) only once.
