Abstract
The present invention discloses a method for measuring an intensity of a part of an electromagnetic spectral range, and an electronic device implementing the method. The method comprises the steps of providing an electronic device comprising an optical device () comprising at least a first liquid (A) and being placed in front of a sensor (), the optical device () having a transmittance of the part of the electromagnetic spectral range depending on an orientation of at least the first liquid (A); measuring a first intensity of the electromagnetic (EM) spectral range; changing the orientation of at least the first liquid (A); measuring a second intensity of the electromagnetic spectral range; and calculating an intensity of the part of the electromagnetic spectral range from the difference between the first intensity and the second intensity. Consequently, an intensity for a part of the EM spectral range can be measured without the need for a sensor dedicated to this part of the EM spectral range. In particular, an optical element based on the electrowetting principle is used in a mobile phone to measure the intensity of UV radiation.
