Abstract

The invention pertains to a solar sensor that includes a first modulator that is transparent to electromagnetic waves within a spectrum, and an additional modulator that is at best slightly transparent to the electromagnetic waves within the spectrum. The additional modulator features a belt-shaped region of varying widths that is arranged on the outside of the first modulator and partially covers the first modulator, and a photodetector that receives the electromagnetic waves and is covered by the first modulator.
