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.

Claims

1-15. -15. (canceled)

16. 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.

17. An arrangement according to claim 16, wherein said receiver device comprises a lens system of an electronic infrared camera and said converter device comprises a cell array of said electronic infrared camera.

18. An arrangement according to claim 16, wherein said receiver device comprises a radio receiver arranged to receive a positioning signal from a satellite and said converter device comprises a positioning module arranged to determine a geographical position on the basis of the positioning signal, a memory device arranged to contain pre-stored data, and a controller arranged to retrieve from the memory device a piece of the pre-stored data on the basis of the geographical position and to produce said electrical signal on the basis of said piece of the pre-stored data.

19. An arrangement according to claim 18, wherein said piece of the pre-stored data comprises information on at least one of the following features of a physical environment that corresponds with said geographical position:

landscape shapes, roads, and buildings.

20. An arrangement according to claim 18, wherein said radio receiver and said positioning module are arranged to use at least one of the following:

a positioning signal of the GPS (Global Positioning System), a positioning signal of the Galileo positioning system, and a positioning signal of the GLONASS positioning system.

21. A display apparatus 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.

22. A display apparatus according to claim 21, wherein the display apparatus further comprises a helmet, said transparent sheet being a visor of the helmet.

23. A display apparatus according to claim 21, wherein the display apparatus further comprises another transparent sheet having another electrically switchable diffractive optical area, a frame of goggles having a radio receiver, and a control unit including said receiver device, said converter device, and a radio transmitter arranged to establish a data transfer link from the control unit to the goggles, said transparent sheet being a first lens of the goggles and said other transparent sheet being a second lens of the goggles.

24. A display apparatus according to claim 21, wherein the display apparatus further comprises a breathing mask, said transparent sheet being an eye shield of the breathing mask.

25. A method for presenting information in a visual form, the method comprising:

receiving electromagnetic radiation that is outside a visual spectral region,

producing an electrical signal at least partly on the basis of information carried by said electromagnetic radiation,

using a transparent sheet that has an electrically switchable diffractive optical area for displaying information carried by said electrical signal and the electromagnetic radiation represents one of the following;

ultraviolet radiation and X-rays.

26. A method according to claim 25, wherein said electromagnetic radiation is received with a lens system of an electronic infrared camera and a cell array of said electronic infrared camera is used for producing said electrical signal.

27. A method according to claim 25, wherein said electromagnetic radiation is received with a radio receiver that is adapted to receive a positioning signal from a satellite and said electrical signal is produced by determining a geographical position on the basis of the positioning signal, by retrieving from a memory device a piece of pre-stored data on the basis of the geographical position, and by producing said electrical signal on the basis of the piece of the pre-stored data.

28. A method according to claim 27, wherein the piece of the pre-stored data comprises information on at least one of the following features of a physical environment that corresponds with said geographical position:

landscape shapes, roads, and buildings.

29. A method according to claim 27, wherein at least one of the following is used for determining the geographical position:

a positioning signal of the GPS (Global Positioning System), a positioning signal of the Galileo positioning system, and a positioning signal of the GLONASS positioning system.
