Abstract
An optical device includes an imaging system provided to generate a plurality of images being distributed over an imaging plane. It further includes a micro-lens-array, MLA, wherein micro-lenses are assigned to individual images and are provided to form channels of light beams by projecting the individual images towards a projecting plane. An optical expander is arranged between the MLA and the projecting plane and includes an input surface and least two output surfaces. The optical expander is provided to fan out and direct the channels of light beams onto the projecting plane, such that individual projections of the individual images are formed on the projection plane. An overall projection is formed on the projection plane by superimposing the individual projections.
