Abstract

Disclosed is an arrangement for detecting first light (L1) and second light (L2), with the first light (L1) and second light (L2) having no wavelength in common. The arrangement includes a first effective detector area (D1) and a second effective detector area (D2). The first effective detector area (D1) is exposed to the first light (L1) and/or second light (L2) different from the first light (L1) and/or second light (L2) to which the second effective detector area (D2) is exposed when the arrangement is exposed to spatially uniformly distributed first light (L1) and second light (L2). The difference between the first light (L1) and/or second light (L2) to which said first detector area (D1) and second detector area (D2) are exposed to can be a difference in intensity and/or difference in an angle of incidence relative to the arrangement.
