Недостатком данного устройства вл етс отсутствие обратной св зи по каналам н перекрестного переключени светового потока с одного канала на другой.The disadvantage of this device is the lack of feedback through the channels of n cross-switching the luminous flux from one channel to another.

Цель изобретени - расширение функциональных возможностей оптического управл емого элемента путем обеспечени перекрестного переключени каналов и пр мой и обратной св зи по каждому из каналов.The purpose of the invention is to enhance the functionality of the optical controlled element by providing cross channel switching and forward and feedback on each of the channels.

Указанна цель достигаетс тем, что в оптический управл емый элемент , содержащий поворотное зеркалоThis goal is achieved by the fact that the optical controlled element containing a rotating mirror

Claims

the fixed plate 3 of the magnetic conductor of the Hz material, a group of optical fibers 4-6, of which the optical fibers b are closed. The ends of the light guides 4-6 are fixed in a sealed, light-tight housing 7 along forming angles of Stress-reflection differing by a double deflection angle JL of the movable plate 1. The angle cL is determined by the position of the fixed plate 3 and the stop 8. The electromagnet 9 serves to control the movable plate 1 the light guides 46 are fixed above the mirror pad 2 so that for the switched group the angles along which they are directed have a common vertex on the axis of rotation of the mirror pad 2. In order for the light flux from one light guide and, after reflection from the mirror site, it was unambiguously unique to only one fiber, various methods of focusing can be used; For example, the fabrication of optical fibers from a light-focusing fiber with a parabolic refractive index distribution across the diameter, installation of focusing microlenses at the ends of the optical fibers, or making terminations of optical fibers with a cone-shaped transition, which allows to obtain a collimated light beam. Different groups of switching channels can be located both in the same plane and in different planes. The drawing shows one plane of optical fibers with two switching groups: rpi on 4 and 4 - 5, and closed-loop light 6, realizing cross-switching and group and 64 / realizing switching. The device works as follows. In the initial state, the magnetically controlled plates 1 and 3 are open, and the movable plate 1 lies on the stop 8, which makes it possible to eliminate the spread of the deflection angle of the movable plate 1. Between the groups of optical fibers 4-6, there is an initial correspondence L established by optical communication through the mirror plate 2 of the movable plate 1. The light fluxes from the optical fibers 4 4j fall on the inputs of the optical fibers, respectively, reflected from the mirror platform 2 of the moving plate 1. At the same time, the light fluxes do not fall on the inputs of the optical fibers S. and 6., lb .. 4a. 4e L5. When voltage is applied to the electromagnet 9, the movable plate 1 under the action of the magnetic field of the electromagnet 9 closes with the fixed plate 3 and fixes the new position of the mirror pad 2 relative to the optical fibers 4-6. In this case, a different angle of incidence of the light fluxes from the optical fibers to the mirror site 2 is established. A new correspondence L arises between the groups of optical fibers 4-6. The light fluxes from the optical fibers to the inputs of the optical fibers fall, respectively, and from you-Q i the course of the optical fiber 6 to the input of the optical fiber 5. Thus, the new correspondence .a H Fa-5, -. and cross-switching of the light flux of the light guide 4 from the light guide 5 to the light guide b, the light flux of the light guide 4 from the light guide 5 to the light guide 5,. When the voltage is removed from the electromagnet 9 under the action of elastic forces, the movable plate 1 opens with the fixed plate 3 and rests on the stop 8. The proposed device solves the problem of simultaneously opening, switching, and cross-switching multiple light streams from one group of optical fibers to another .
