Abstract:
1. A projection arrangement comprising: a light source; a light modulator, arranged following the light source and onto which light from the light source may be directed, said light being modulated by the light modulator under the control of a control device on the basis of predetermined image data, to generate an image; projection optics arranged following the light modulator for projecting said image onto a projection surface, wherein the control device comprises a control unit and a correcting unit, said correcting unit pre-distorting the predetermined image data such that a non-linear distortion caused by the projection optics is compensated, wherein said control unit controls the light modulator based on the pre-distorted image data, and wherein the rejection optics have a residual distortion of greater than or equal to two percent and of less than or equal to fifty percent.
