A vehicle ( 10 ) includes an infrared imaging system ( 11 ). The system includes an infrared camera ( 12 ) positioned in the center of the front grille of the vehicle. The infrared camera includes a window ( 13 ) that has a holographic fringe pattern ( 14 ) which cooperates with visible light rays ( 27, 47, 52, 57 ) to generate an image ( 29 ) that is visible at a location spaced from the vehicle. The visible image may, for example, be a trademark or other symbol identifying the manufacturer of the vehicle. Infrared radiation ( 31 ) passes through the element and the structure thereof without significant change, and is detected by an infrared detector ( 33 ). A visible image corresponding to the infrared radiation is ultimately displayed by a head up display ( 19 ) on a portion ( 16 ) of the vehicle windshield ( 17 ).

1. An apparatus comprising an element having a surface and structure, the structure comprising a holographic fringe pattern embossed in the surface of the element, the structure operable to cooperate with visible light rays to generate an image which is visible at a location spaced from said element
1. An apparatus comprising an element having a surface and structure, the structure comprising a holographic fringe pattern embossed in the surface of the element, the structure operable to cooperate with visible light rays to generate an image which is visible at a location spaced from said element, wherein infrared radiation passes through said element and said structure thereof without significant change. 2. An apparatus according to claim 1, wherein said element includes a sheet and a member made of different materials, said sheet being coupled to said member and said sheet including said structure. 3. An apparatus according to claim 1, wherein said visible light rays, prior to cooperation with said structure of said element, are free of said image. 4. An apparatus comprising an element having a surface and an image-generating structure, the structure comprising a holographic fringe pattern embossed in the surface of the element, the structure operable to cooperate with visible light rays to generate an image which is visible at a location spaced from said element by being configured so that at least a portion of visible radiation arriving at said element on a first side thereof is influenced by said structure and thereafter travels away from said element on said first side thereof and represents a elected image which is different from an image of said element and which is visible to a naked eye at a location spaced from said element on said first side thereof, and said structure being further configured so that infrared radiation arriving at said element on said first side thereof passes through said element and said structure to a second side of said element in a manner free of any significant influence by said structure. 5. An apparatus according to claim 4, further comprising a light source which emits visible light rays, wherein said structure cooperates with light rays emitted by said light source to generate said selected image. 6. An apparatus according to claim 5, wherein said surface comprises one of a front surface and a rear surface, said location being on a side of said element corresponding to said front surface, and said light source projecting light rays onto one of said front and rear surfaces. 7. An apparatus according to claim 4, wherein said element includes a material and a dye disposed in said material. 8. An apparatus according to claim 4, wherein said element is a polymeric transmissive material that passes infrared radiation having a wavelength in the range of approximately 8-12 micrometers. 9. An apparatus according to claim 4, further comprising a frame, said frame supporting said element and including a light source, wherein said light source emits light rays that cooperate with said structure to generate said selected image. 10. An apparatus according to claim 4, further comprising an infrared detector, said infrared detector receiving infrared radiation which has passed through said element. 11. An apparatus according to claim 10, wherein said infrared detector is an uncooled detector, said uncooled detector having an array of detector elements for detecting infrared radiation impinging thereon. 12. An apparatus according to claim 1, further comprising a lens section positioned optically between said element and said infrared detector, said lens section focusing infrared radiation which has passed through said element onto said infrared detector. 13. An apparatus according to claim 12, further comprising a circuit and a display, said display including a display surface, said circuit receiving from said infrared detector electrical information representative of infrared radiation detected by said infrared detector, and providing on said display surface a visible image of a scene corresponding to the infrared radiation. 14. An apparatus according to claim 13, further comprising a vehicle with a windshield, said display surface being an inner surface of said windshield, said vehicle including sa id display, said element, said lens section, and said infrared detector. 15. An apparatus according to claim 4, wherein said element includes a sheet and a member made of different materials, said sheet being coupled to said member and said sheet including said structure. 16. An apparatus according to claim 4, wherein said visible radiation arriving at said element is free of said selected image. 17. A method comprising the steps of:generating a visible image by causing at least a portion of visible radiation arriving at an element on a first side thereof to be influenced by structure of said element and to thereafter travel away from said element on said first side thereof while representing a selected image which is different from an image of said element and which is visible to a naked eye at a location spaced from said element on said first side thereof, the element having a surface, the structure comprising a holographic fringe pattern embossed in the surface of the element; andpassing infrared radiation which arrives at said element on said first side thereof through said element and said structure to a second side of said element in a manner free of any significant influence by said structure. 18. A method according to claim 17, further comprising the step of generating visible light rays with a light source, said light rays being affected by said structure to generate said selected image. 19. A method according to claim 17, further comprising the step of selecting as said structure the holographic fringe pattern. 20. A method according to claim 17, further comprising the step of focusing infrared radiation which has passed through said element onto an infrared detector using a lens section, said lens section being positioned optically between said element and said infrared detector. 21. A method according to claim 17, including causing said visible radiation which arrives at said element to be free of said selected image.
