Abstract:
1. An arrangement for projecting a color video image onto a projection surface, the image being composed of image points, said arrangement comprising: at least one light source, which emits a light bundle and has a variable intensity; a deflection device, which deflects the light bundle across the projection surface, and two-stage transformation optics for angular magnification of said light bundle, which are arranged between the deflection device and the projection surface and comprise two partial systems having positive refractive power, wherein an entrance pupil of the transformation optics is located in front of a first lens vertex of the transformation optics, and an exit pupil of the transformation optics is located between a lens vertex of the last lens of the transformation optics and the projection surface, and a stop is arranged substantially coplanar with the exit pupil.
