Abstract

Изобретение относится к оптической голографии, предназначено для записи дифракционных элементов и может найти применение при изготовлении дифракционных элементов, радужных голограмм, при защите товаров и ценных бумаг от подделок, в полиграфии. Изобретение также может быть использовано в системах оптической памяти и оптической обработки информации. В устройстве для записи дифракционных элементов, содержащем оптически связанные источник света, узел отклонения пучка света, первую линзу, включающий в себя первую призму узел разделения пучка света, фокусирующий объектив, регистрирующую среду, привод перемещения регистрирующей среды и узел управления, электрически связанный с источником света, узлом отклонения пучка света, приводом перемещения регистрирующей среды, узел отклонения пучка света выполнен в виде установленных последовательно вдоль оптической оси второй линзы и двух зеркальных дефлекторов, причем расстояние I между плоскостью зеркала любого из двух дефлекторов и точкой фокусировки света первой линзой выбрано из соотношенияI<BTff/Fd,где коэффициент В = 0.1-0.5, Т - период решетки дифракционного элемента в регистрирующей среде, f- фокусное расстояние второй линзы, f-фокусное расстояние первой линзы, f- фокусное расстояние фокусирующего объектива, d- диаметр пучка на входе второй линзы.The invention relates to optical holography, is intended to record diffractive elements and can be used in the manufacture of diffractive elements, rainbow holograms, in the protection of goods and securities from fakes, in printing. The invention can also be used in optical memory systems and optical information processing. In a device for recording diffractive elements containing an optically coupled light source, a light beam deflection assembly, a first lens, including a first prism a light beam separation unit, a focusing lens, a recording medium, a recording medium movement drive, and a control unit electrically connected to the light source , the node of the deflection of the light beam, driven by the movement of the recording medium, the node of the deflection of the light beam is made in the form of a second lens of the first deflectors, the distance I between the plane of the mirror of any of the two deflectors and the point of focusing the light by the first lens is chosen from the relation I <BTff / Fd, where the coefficient B = 0.1–0.5, T is the period of the diffraction element grating in the recording medium, f is the second focal length lenses, f-focal length of the first lens, f-focal length of the focusing lens, d-diameter of the beam at the entrance to the second lens.
