SOLAR SENSOR

摘要

Disclosed is a solar sensor comprising a first modulator (1) that is permeable to electromagnetic waves within a certain spectrum, an additional modulator (2) which is no more than slightly permeable to the electromagnetic waves within said spectrum, and a photo detector (3) which receives the electromagnetic waves and is covered by the first modulator. The additional modulator is disposed on the outside of the first modulator, partially covers the first modulator, and is provided with a belt-shaped area (2a), the width (w) of which varies.
