Abstract: The invention relates to the optoelectronics, in particular to devices for image obtaining by means of optical fibres.The device for image obtaining by means of optical fibres, according to the first variant, includes a perforated screen, to which there are fixed the ends of the optical fibres with the possibility of forming the given image, the other ends of the optical fibres are bundled together, forming a light detector, and a light source placed opposite to it. Novelty of the invention consists in that the perforated screen contains a frame and, mounted therein, band elements, into each of them the ends of the optical fibres being fixed in a row. The form and the size of the frame correspond to the form and size of the given image.The device for image obtaining by means of optical fibres, according to the second variant, includes a perforated screen, to which there are fixed the ends of the optical fibres with the possibility of forming the given image, the other ends of the optical fibres are bundled together, forming a light detector, and a light source placed opposite to it. Novelty of the invention consists in that it additionally contains a body, wherein there is installed the perforated screen, containing band elements, into each of which the ends of the optical fibres being fixed in a row, and placed in front of the screen, a transparent plate onto which there is deposited a film, the contour of which is determined by the form of the given image.The device for image obtaining by means of optical fibres, according to the third variant, includes a screen, to which there are fixed the ends of the optical fibres with the possibility of forming the given image, the other ends of the optical fibres are bundled together, forming a light detector, and a light source placed opposite to it. Novelty of the invention consists in that it additionally contains a plate, placed in front of the screen, wherein are made cuts, the form and size of the assemblage of which constitute the given image, at the same time onto each cut there is placed an element, the form and size of which correspond to the form and size of the cut, and to each element there are fixed the ends of the optical fibres.The device for image obtaining by means of optical fibres, according to the fourth variant, includes a perforated screen, into the orifices of which there are placed the ends of the optical fibres, the other ends of the optical fibres are bundled together, forming a light detector, and a light source placed opposite to it. Novelty of the invention consists in that onto the screen there is fixed an information element, the form and size of which are determined by the given image; at the same time the ends of the optical fibres are fixed to the element.The device for image obtaining by means of optical fibres, according to the fifth variant, includes a means for reproduction of the given image, to which there are fixed the ends of the optical fibres, the other ends of the optical fibres are bundled together, forming a light detector, and a light source placed opposite to it. Novelty consists in that the means for reproduction of the given image contains separate elements, the assemblage of which determines the form of the given image, at the same time some ends of the optical fibres are fixed to each of the elements, and the other ends of the optical fibres of each element apart are bundled together, the number of which corresponds to the number of separate elements.
