Abstract
A device determines and subsequently corrects the dispersive influence on a measurement made according to the principles of phase or pulse modulation along a visible range. The device has an element for emission of electro-magnetic radiation with two carrier wavelengths in the border regions of the visible spectrum. After passing through a volume of atmosphere to be probed, and reflection, the radiation is received and the dispersive influence, for instance, on the distance measurements, is calculated and corrected.
