ABSTRACT:
The invention relates to an image projection module (1) comprising, in this order, an illumination system (3) and an image display system (13) having at least one display panel (15) for modulating an illumination beam to be supplied by the illumination system (3) with image information. The illumination system (3) comprises an integrator system (19) having an exit surface which is located in an exit plane. First reflecting means (33; 43) are present in the exit plane of the integrator system (19) and the module (1) further comprises second, selectively reflecting means (39). An optical system (31) for at least partly imaging the exit surface via the second reflecting means on the first reflecting means is arranged between the first and the second reflecting means.
