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.

Abstract: An optical sensing device for using light to locate objects or features in a field of view comprises a light source; a controllable lens having two states and being controllable between them, for example a multifocal lens having two or more foci for focusing light from the light source; and a sensor able to sense light reflected from an object, to determine information of the object. The use of two or more foci adds dynamic range to optical sensing to allow for reliable detection over a wide range of distances.
