Method and arrangement for presenting information in a visual form

An arrangement for presenting information in a visual form, the arrangement comprising:

• a receiver device adapted to receive electromagnetic radiation that is outside a visual spectral region,
• a converter device adapted to produce an electrical signal at least partly on the basis of information carried by said electromagnetic radiation, and
• a transparent sheet having an electrically switchable diffractive optical area adapted to display information carried by said electrical signal and the receiver device comprises a sensor for one of the following:
• ultraviolet radiation and X-rays.
