Patent ID: 7795564

Claim:
An optical system comprising a first lens and a first sensor unit for sensing electromagnetic radiation, wherein the optical system is arranged such that incident electromagnetic radiation that originates from a scene outside of the optical system reaches the first sensor unit by passing via the first lens and by following a beam path from the first lens to the first sensor unit, wherein the optical system further comprises a micromirror matrix unit, which comprises a plurality of micromirror elements and which is arranged in the beam path, wherein the micromirror matrix unit is set in at least a first or a second state, wherein in the first state the micromirror matrix unit reflects the incident electromagnetic radiation which reaches the micromirror matrix unit from the first lens so that the electromagnetic radiation reaches the first sensor unit, wherein in the second state the micromirror matrix unit reflects the incident electromagnetic radiation which reaches the micromirror matrix unit from the first lens so that the electromagnetic radiation does not reach the first sensor unit.
