Definitions

  • the two lighting sources are advantageously designed to be dimmable, ie their brightness can be adapted to the ambient brightness.
  • the wavelength filter array is applied, for example, to the large area corresponding to the radiation level.
  • Array is understood to mean all regular arrangements of filter elements, in addition to a grid-like arrangement also strip-like arrangements, the strips being able to run vertically, but also with large deviations from the vertical, provided that a three-dimensional view is still possible in the first operating mode.
  • translucent and opaque filter elements of course, grayscale filter elements and polarization filters can of course also be used in an equivalent manner.
  • the ratio of the area of the surface areas occupied by filter elements that are translucent in predetermined wavelength ranges to the surface areas occupied by opaque filter elements, based on the surface areas occupied by opaque filter elements on the edge to the coupling narrow surfaces is chosen to be smaller than, for example, in the middle of the second illumination source .
  • light is increasingly coupled out of the light guide in the middle of the light guide due to the particles opposite the edge.
  • Two filter arrays of the same type are preferably used, which are arranged without optical distance from one another in order to avoid moor effects.
  • the filter arrays can also be designed entirely without opaque filter elements.
  • an optically scattering film is provided as a means for uniform illumination in the second operating mode between the wavelength filter array and the light guide, which preferably reflects the light in white diffusely or is designed to be remitting.
  • a film is structureless and has homogeneous optical properties such that it diffusely scatters incident light. It can therefore not only be thin, but also mechanically very flexible and is also inexpensive to manufacture.
  • it is therefore provided to remove the film between the wavelength filter and the light guide in order to switch to the first operating mode. This can be done by hand, but preferably by means of a roll-up and roll-off mechanism.
  • FIG. 8 shows a schematic illustration of the interaction of the first and the second illumination source for the purpose of homogeneous illumination of the image display device
  • FIG. 9 shows another exemplary wavelength filter array for use in the first embodiment of arrangements according to the invention (detail illustration)
  • FIG. 29 shows a further special embodiment of a wavelength filter array
  • FIG. 30 shows an electrophoretic wavelength filter array
  • the opaque filter elements of the wavelength filter array 3 are diffusely scattered on the side facing the viewer, for example provided with a matt white lacquer. As a result, light which is coupled out on the side facing the filter array 3 is diffusely scattered back.

Abstract

L'invention concerne un ensemble pour afficher en deux ou trois dimensions, cet ensemble comprenant les éléments suivants : un dispositif de reproduction d'images (1) composé d'une pluralité d'éléments d'images transparents, sur lesquels des informations concernant des images peuvent être présentées sous plusieurs perspectives ; un ensemble filtre de longueurs d'ondes (3) ; un dispositif d'éclairage à commande et fonctionnant selon au moins deux modes. Dans le premier mode de fonctionnement, une lumière est émise par une première source lumineuse (2) placée derrière l'ensemble filtre de longueurs d'ondes (3) et traverse au moins une partie des éléments filtrants transparents, puis une partie associée des éléments d'images du dispositif de reproduction d'images (1), pour arriver à l'observateur (7) qui voit ainsi la scène ou l'objet en trois dimensions. Dans un deuxième mode de fonctionnement, une deuxième source d'éclairage (4) émet une lumière qui traverse les éléments d'images du dispositif de reproduction d'images (1), sans toutefois passer par les éléments filtrants de l'ensemble filtre de longueurs d'ondes (3), laquelle lumière arrive jusqu'à l'observateur (7) qui voit la scène ou l'objet au moins partiellement en deux dimensions, ce deuxième mode de fonctionnement faisant en outre appel à des moyens servant à homogénéiser l'éclairage.
