Abstract
Device for generating polarized electromagnetic radiation has a diffuser and a polarizer. The diffuser is arranged in a beam path of the electromagnetic radiation. The polarizer is arranged in the beam path of the electromagnetic radiation, to be precise downstream of the diffuser in the direction of propagation of the electromagnetic radiation. The polarizer has a reflective side facing the diffuser, said reflective side being at least partly reflective to the electromagnetic radiation. The polarizer transmits electromagnetic radiation having a predefined polarization and reflects electromagnetic radiation not having the predefined polarization back to the diffuser. The diffuser scatters, in a non-polarization-maintaining manner, at least one portion of the reflected-back electromagnetic radiation not having the predefined polarization.
