Abstract: An object is identified or tracked within a volume by projecting a light beam encoded with one or more predefined properties to have a predefined optical structure into the volume. A detector captures light from the predefined optical structure reflected from the volume. By analyzing one or more characteristics of light from the predefined optical structure reflected from the object, the object is segmented from the volume.

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: A method and system for generating light pattern using reflective polygons are provided herein. The method may include: rotating at least one polygon having a plurality of reflective facets along a rotation axis parallel to the facets; transmitting a light beam on the facets of the polygon; tilting the light beam relative to the polygon in parallel to the rotation axis so that the light beam hits each of the facets at a different tilt angle, thereby producing a light pattern comprising a plurality of lines; and controlling at least one of: the light intensity, the rotating, and the tilting, so as to produce an adjustable light pattern transmitted at a scene.

Abstract: Apparatus for generating a dynamic structured light pattern for optical tracking in three-dimensional space, comprises an array of lasers, such as a VCSEL laser array, to project light in a pattern into a three-dimensional space; and an optical element or elements arranged in cells. The cells are aligned with subsets of the laser array, and each cell individually applies a modulation, in particular an intensity modulation, to light from the laser or lasers of the subset, to provide a distinguishable and separately controllable part of the dynamic structured light pattern. A method of generating a structured light pattern is disclosed, in which light is provided from an array of lasers, and light is individually projected from subsets of the array of lasers to provide differentiated parts of the structured light pattern.

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.
