Abstract
There is provided an optical display system, including a light source, a control unit, and an array of at least two juxtaposed double grating elements, each of the elements comprising a first grating and a second grating, spaced apart at a constant distance from each other, each of the two gratings having at least two edges and comprises at least one sequence of a plurality of lines, wherein the spacing between the lines gradually changes from one edge of the grating to the other edge, and wherein the first grating diffracts a light wave from the light source towards the second grating and is further diffracted by the second grating as an output light wave in a given direction.

An optical display system, comprising:
- a light source;
- a control unit;
- and
- an array of at least two pixels, each of the pixels being a juxtaposed double grating element, comprising a first grating and a second grating spaced apart at a constant distance from each other, each of the two gratings having at least two edges, at least one sequence of a plurality of lines and an apertures,
- the spacing between the lines gradually changing over the aperture of the gratings,
- the first grating diffracting a light wave from the light source towards the second grating, the light wave further diffracted by the second grating as an output light wave in a given direction,
- wherein for each of the pixels the direction of the output light wave from the second grating is separately, dynamically and externally controlled by the control unit.
