Изобретение относитс к голографии .This invention relates to holography.
Известны способы получени изображени путем записи и восстановлени голограмм на регистрирующих средах, 5 В качестве которых могут быть выбраны как галогеносодержащие высокоразрешающие фотоматериалы, так и термопластики , фотохромные стекла l.Methods are known for obtaining an image by recording and restoring holograms on recording media, 5 which can be selected from both halogen-containing high-resolution photographic materials and thermoplastics, photochromic glasses l.
Ближайшим известным техническим решением вл етс способ получени изображени путем записи голограмм на полупроводниковой пластине, состо щей из халькогенидного стекла, 5 прозрачного электронагревательного сло и подложки и восстановлени изображени при записи голограммы на длине волны ,633 мкм C2l.Пластинку стекла толщиной .до 0,8 мм нагре-20 вают от комнатной (20с) до высокой () температуры. В результате этого край оптического поглощени сдвигаетс линейно с %ч 1,310 э В/град в сторону длинных волн, обес-25 печива достаточное поглощени/ записывающего света. После охлаждени край поглощени сдвигаетс в обратную сторону, поглощение уменьшаетс и свет X 0,633 мкм уже считывает вThe closest known technical solution is a method of obtaining an image by recording holograms on a semiconductor wafer consisting of chalcogenide glass, 5 transparent electric heating layer and a substrate, and restoring the image when recording a hologram at a wavelength of 633 micron C2l. mm heat-20 is from room temperature (20s) to high () temperature. As a result, the optical absorption edge shifts linearly from% h to 1.310 oh V / deg towards the long waves, providing sufficient absorption / recording light to the furnace. After cooling, the absorption edge shifts in the opposite direction, the absorption decreases and the light X 0.633 µm already reads in
основном фазовую запись, без разрушени самой голограммы.mainly phase recording, without destroying the hologram itself.
