Description

Изобретение относитс  к голографии , а именно к регистрирующим средам дл  записи стационарных ronorpaiMM с помощью излучени  неодимового и рубинового лазеров, и может быть исполь- 5 зовано дл  регистрации оптической информации и получени  голографических элементов (рельефных голографических дифракционных решеток, линз, светоделителей , корректоров) .пригодных в 10 видимой и ближней ИК-области спектра. Одной из основных задач голографии,  вл етс  поиск высокоэффективных ре- гистрирукхцих сред. Под высокой эффективностью подразумеваетс  не только 15 обеспечение высоких значений таких основных параметров, как чувствительность , дифракционна  эффективность и разрешающа  способность, но и наличие р да не менее важных свойств таких, 20 как стабильность во времени, короткие времена записи, большое соотношение сигналов (шум, устойчивость к лазерному излучению и др.The invention relates to holography, in particular to recording media for recording stationary ronorpaiMM using radiation of neodymium and ruby lasers, and can be used to record optical information and obtain holographic elements (embossed holographic diffraction gratings, lenses, beam splitters, correctors). suitable in 10 visible and near infrared spectral regions. One of the main tasks of holography is to search for highly efficient recording media. High efficiency means not only ensuring high values of such basic parameters as sensitivity, diffraction efficiency and resolution, but also the presence of a number of equally important properties such as stability over time, short recording times, a large ratio of signals (noise, resistance to laser radiation, etc.

Основными требовани ми  вл ютс  25 также технологичность и простота изготовлени  регистрирующей среды, что определ ет возможность изготовлени  носител - информации большой площади .30The main requirements are also the manufacturability and ease of manufacture of the recording medium, which determines the possibility of manufacturing the carrier — large-area information .30

Особо актуальным  вл етс  поиск регистрирующих сред дл  ИK-oблacтJ спектра, максимально удовлетвор ющих указанным выше требовани м,поскольку в ИК-области спектра отсутствуют эффективные регистрирующие среды.Of particular relevance is the search for recording media for the IC-spectrum of the spectrum that best meet the above requirements, since there are no effective recording media in the IR region of the spectrum.

; Известен р д регистрирующих сред, чувствительных в ИК-области спектра. К ним относ тс  металлические пленки/ полупроводниковые материалы, органические фотохромные материалы, термопластики , желатиновые, слои.; A number of recording media sensitive in the infrared region of the spectrum are known. These include metallic films / semiconductor materials, organic photochromic materials, thermoplastics, gelatin, layers.

Наилучшими по основным параметрам  вл ютс  металлические плен ки висмута , имеющие достаточно высокую чувствительность пор дка 10 Дж/см - в широкой области спектра, в том числе и в ИК-области 1.The best in basic parameters are metal films of bismuth, which have a rather high sensitivity of the order of 10 J / cm in a wide spectral range, including in the infrared region 1.

Недостаток пленок Bi  вл етс  о.кисление 1слоев в атмосфере, что приводит к изменению их физических свойств.The lack of Bi films is the oxidation of the layers in the atmosphere, which leads to a change in their physical properties.
