Description

The utility model relates to the field of image transmission and telemetry and can be used to transmit images at a distance along the optical fiber and reproduce the image in an enlarged form with optical lenses.

A device for image transmission [1] TV KVN-49, (see the site http://www.minp.ru/wiki/KBH-49) is known. It consists of a television receiver with an 18LK1B kinescope and a magnifying lens. The image size of the round screen of the tube was 105 × 140 mm. To increase the size of the image, a separately attached magnifying plastic lens filled with glycerin or distilled water was substituted. The lens magnified the image one and a half times, and reproduced the image with strong distortion at the edges.

The disadvantages of the prototype considered include the small image size, low image quality of the image.

A device for transmitting an image [2] is a liquid crystal (LCD) screen in which a semiconductor LED (LED) is used as an image source. (see the website http://www.ledsen.ru/faq/index.php) The LCD screen consists of a set of semiconductor LEDs which is a unit of image, a pixel. Depending on the size and resolution of the screen, the number of LEDs making up a pixel can range from three to several

dozens. For the formation of large information screens, LEDs are combined according to the matrix principle.

The disadvantages of the prototype considered should be attributed to the complexity of the design due to the large number of used electronic elements, this leads to unreliability in operation and high cost.

The task solved by the utility model is to simplify the design, increase reliability and reduce its cost.

The problem is achieved in that the claimed device inside the advertising and information installation contains a device for displaying information with a high resolution screen, such as a computer LCD monitor (internal screen). A capillary lattice with holes is fixed on the inner screen, which divides the screen into cells in matrix order. The holes in the cells correspond to the diameter of the used optical fiber. A fiber is fixed in each hole of the grill so that the end of the fiber rests against the inner screen. At the other end of the fiber, each fiber is connected to one optical magnifying lens. Between themselves, the lenses are rigidly combined in a matrix order and in accordance with the location of the cells on the capillary lattice. Lenses are fixed on the surface of a transparent material which is a screen of an advertising and information installation (external screen). Each magnifying lens is connected to the optical fiber in the strict order in which the optical fiber is connected to the cells of the capillary lattice, i.e. the cell number of the matrix of holes in the capillary lattice corresponds to the lens number of the matrix of the external screen.

Distinctive features from prototypes are:

- the source of information is a screen with high image quality;

- between the internal and external screen, fiber optic communication is used;

- one electronic device is used having low power consumption, i.e. source of information (internal screen);

- the external screen consists of many non-electronic devices, which increases the reliability of the structure, its low cost.

Thus, by upgrading the first prototype to the modern level of technology and simplifying the second prototype, while practically without compromising its technical characteristics, the problem posed by the utility model is solved.

The image transmission device in the advertising and information installation with the claimed combination of distinctive features in the patent and scientific literature was not found.

The image transfer device in the advertising and information installation is illustrated in the drawing, which shows the connection diagram and layout of the devices used.

Inside the housing of the advertising and information installation (1), there is an internal screen (2), a capillary lattice (3) is fixed on it. The optical fibers (4) from the screen pass through the holes in the grill, and are attached to the lenses (5), which create an external installation screen. In the drawing, there is no part of the optical fiber and that part of the external screen that closes the view to the internal screen.

The device operates as follows.

The inner screen (2) located, for example, on the rear wall of the housing of the advertising and information installation, displays information. Each optical fiber (4), mounted in its cell on the capillary grating (3), absorbs the image of the internal screen, and transmit the image to an optical magnifying lens. In this case, the loss of power of the light flux passing through the optical fiber at a distance of up to four meters is about 1.5% per meter, which slightly affects the brightness of the transmitted image. An optical lens magnifies an image pixel n times. Lenses are combined into a matrix and mounted on the surface of a transparent material, or by themselves create the surface of the screen. The size and resolution of the screen of an advertising and information installation directly depends on the size of the lenses from which this screen is assembled. Consider an example: on the internal screen, a 15-inch LCD monitor, a capillary lattice is fixed, which divides the screen into 128 × 256 cells. A fiber of 1.5 mm diameter departs from each cell of the capillary lattice, and connects to a lens with a 5-fold magnification on an external screen. Each lens will display a pixel size: 1.5 mm. × 5 = 7.5 mm., Taking into account the inter-lens distance of 0.5 mm., Equal to 8 × 8 mm. The result is an advertising and information installation with a resolution of 128 × 256 pixels will consist of 128 × 256 = 32768 pcs. magnifying lenses and has a size: 128 × 8 mm. = 1024 mm., By 256 × 8 mm. = 2048 mm. At the present stage of technology, an LCD screen with similar dimensions and characteristics has a panel cost of about 2,000,000 rubles. The design of the proposed utility model is much simpler than existing analogues and more energy-efficient, and the cost is an order of magnitude lower.
