1. A light shaping assembly, comprising:
a printed circuit board (PCB);
a two-dimensional (2D) array formed of a plurality of rows, each row comprising a plurality of light sources mounted on the PCB, each light source being a multi color light source operable to selectively emit visible light or infrared light; and
a Fresnel lens configured to redirect a light beam emitted by each light source at an angle increasing as a function of a distance between each light source and a selected point on the PCB so that the light beams emitted by the light sources are collectively directed toward a common target;
wherein each of the plurality of light sources is operable to:
selectively emit a corresponding infrared light pixel modulated with a corresponding digital data stream for inducing a corresponding control instruction in the corresponding light pixel, and
selectively emit a correspond visible light pixel to allow previewing a visible image formed by combining the emitted visible light pixels.
