Abstract: A Time-of-Flight system having a light source which emits first light rays at a first wavelength and second light rays at a second wavelength to an object, the second wavelength being larger than the first wavelength, and a time-of-flight sensor which detects the first light rays at the first wavelength and the second light rays at the second wavelength, and generates first time-of-flight data associated with the detected first light rays and second time-of-flight data associated with the detected second light rays.

Abstract: An illumination device for a light detection device, the light detection device including a light detection sensor and an optical lens portion, wherein the illumination device includes a light source configured to emit light to a scene and a light intensity adapting device configured to adapt a light intensity profile of the light emitted by the light source for at least partially providing a uniform light intensity on the light detection sensor of light reflected from the scene and detected by the light detection sensor through the optical lens portion.
