Optical system for detecting a scanning field

An optical system for detecting a scanning field, comprising:

• a transmitter, including 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;
• and
• at least one optical receiver, including at least one optical filter element for filtering the electromagnetic radiation backscattered and/or reflected in the scanning field, and at least one detector element for detecting the filtered electromagnetic radiation;
• wherein the wavelength of the electromagnetic radiation emitted by the source is variable, and
• wherein the variation of the wavelength occurs as a function of the deflection of the beam path.

A system for controlling an optical system for detecting a scanning field, comprising:

• a transmitter, including 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;
