Abstract
The invention relates to a method and arrangement for extending viewing capability of a user who is looking through a transparent sheet. The transparent sheet can be, for example, a lens of goggles, an eye shield of a breathing mask, a visor of a helmet, or a windscreen of a vehicle. The arrangement comprises a receiver device (101) adapted to receive electromagnetic radiation, e.g. infrared radiation, that is outside the visual spectral region. The arrangement comprises a converter device (102) adapted to produce an electrical signal (111) at least partly on the basis of information carried by the received electromagnetic radiation. The arrangement comprises a transparent sheet (103) that has an electrically switchable diffractive optical area (104) adapted to display information carried by the electrical signal.
