Abstract
A method and system for generating light pattern. The system may include: a light source providing a diverging light beam; a single lens element having first surface with a positive optical power in at least one cross section and a second surface. The second surface is configured to provide a multiplication function of the light beam in that cross section and a predefined intensity light distribution generator in a second cross section.

A light generator system for generating a light pattern in a X-, Y-, Z-axis Cartesian coordinate system, said light generator system comprising:
- a light source providing a diverging light beam directed along the Z-axis;
- a single lens element, said single lens element comprising:
- a first surface having a positive optical power in a first cross section;
- and
- a second surface configured to provide a multiplication function of said beam in said at first cross section;
- and
- a predefined intensity light distribution generator formed on only one of the first and second surfaces, in a second cross section which is different from the first cross section.
A light generator system for generating a light pattern in a X-, Y-, Z-axis Cartesian coordinate system, said light generator system comprising:
- a light source directed along the Z-axis;
- a first lens element having a first surface and second surface, the first surface of the first lens element having a positive optical power in a first cross section;
- a second lens element having a first surface and a second surface, the first surface of the second lens element having a negative optical power, in a second cross section different from the first cross section;
- and
- a multiplication function on at least one of the second surface of the first lens element, the first surface of the second lens elements, or the second surface of the second lens element, in said first cross section.
