Abstract
The invention relates to an optical device, comprising: a lens having an adjustable focal length. According to the invention, a light source which is configured to emit light that is affected by said lens and impinges on at least a first photosensitive element, which is designed to generate a first output signal corresponding to the intensity of light impinging on it, wherein the first photosensitive element is configured to measure only a portion of the intensity distribution of said emitted light, and wherein the light source, the lens and the first photosensitive element are configured such that a change of the focal length of said lens changes the intensity distribution of the emitted light that impinges on the first photosensitive element, so that each focal length of the lens is associated to a specific first output signal generated by the first photosensitive element.
