Projection display having kohler illumination of projection lenses
First Claim
1. A projection display having at least one light source and regularly-disposed optical channels, each comprising at least one field lens, to each of which one object structure to be imaged and at least one projection lens are assigned, wherein for each regularly-disposed optical channel the distance from the at least one projection lens to the object structure corresponds to the focal distance of the projection lens and the distance from the identical object structure to the at least one field lens is chosen such that a Kö
- hler illumination of the at least one projection lens is made possible, and wherein the at least one projection lenses assigned to the regularly-disposed optical channels produce individual projections which are superimposed to form an actual total picture on a screen or a virtual total picture.

Abstract
A projection display having at least one light source and also regularly-disposed optical channels. The optical channels comprise at least one field lens, to which respectively one object structure to be imaged and also at least one projection lens are assigned. The distance of the projection lenses from the assigned object structures corresponds to the focal distance of the projection lenses while the distance of the object structures to be imaged from the assigned field lens is chosen such that a Köhler illumination of the assigned projection lens is made possible. Then the individual projections are superimposed to form the total image.
