Abstract

The invention relates to arrangements for spatial display, and in particular to such arrangements that, by means of wavelength or gray level filter arrays, present an image visible in three dimensions to one or several observers without the use of auxiliary aids such as glasses. In such arrangements, an increased brightness of the 3D display is achieved by means of the arrangement of transparent filters on the filter array according to the invention.
