Abstract
A sensor device for a transportation device includes a sensing apparatus for sensing first electromagnetic radiation having at least one first wavelength, and a covering device for the sensing apparatus. The covering device contains a fluorescent portion includes a fluorescent dye, which has an absorption spectrum and an emission spectrum. The fluorescent portion is transparent to the first electromagnetic radiation having the first wavelength. The fluorescent portion is configured such that, when irradiated with second electromagnetic radiation having a second wavelength in the absorption spectrum of the fluorescent dye, the fluorescent portion emits third electromagnetic radiation in the emission spectrum. The first wavelength and the second wavelength are different.
