The invention relates to an arrangement for projecting an image, which is made of pixels, onto a projection surface, including at least one light source whose intensity can be altered and which emits a light beam, also including a deflection device which deflects the light beam onto the projection surface, and a two-stage transformation lens system which is arranged between the deflection device and the projection surface. The invention also relates to optical systems for adjusting the angle of an incident light beam by means of a two-stage transformation lens. The invention includes a transformation lens system is made up of two partial systems having positive refractive power such that when seen in the direction of the propagation of the light, the entrance pupil is arranged in front of the first lens apex of the transformation lens system and the exit pupil of the transformation lens system is arranged between the lens apex of the last lens and the projection surface, and a diaphragm is arranged inside the exit pupil.

Arrangement for projecting an image onto a projection surface and associated transformation lens system

A video projection system with at least one light source which can be controlled in intensity and generates at least one light bundle and with a deflecting device which deflects the light bundle sequentially to produce picture points of a video picture on a screen by picture and line scanning has two component groups, the first of which contains at least one light source and has a light output from which at least one light bundle exits, while the second component group contains the deflecting device and has a light input through which a light bundle can be imaged into the deflecting device. Further, a light transmission device is provided which enables the light output of the first component group to be optically connected with the light input of the second component group.
