Abstract
An optical system for detecting a scanning field, a system for controlling the optical system as well as a method for controlling the optical system, the optical system having at least one transmitter comprising at least one source for emitting electromagnetic radiation and at least one deflection unit for deflecting the beam path of the electromagnetic radiation emitted by the source into the scanning field. The optical system furthermore has at least one optical receiver comprising at least one optical filter element for filtering the electromagnetic radiation scattered back and/or reflected in the scanning field and at least one detector element for detecting the filtered electromagnetic radiation. The essence of the invention lies in the fact that it is possible to vary the wavelength of the electromagnetic radiation emitted by the source and that the variation of the wavelength occurs as a function of the deflection of the beam path.
