Abstract
ГОЛОГРАФИЧЕСКИЙ ИНТЕРФЕРОМЕТР реального времени, содержащий лазер, светоделитель, системы формировани предметного и опорного пучков и регистрато1р голограммы, о т- личающийс тем, что, с це- лыо измерени автокоррел ционной функции рассе нного излучени , интерфе- рсметр снабжен фазовые модул тором, линзой и блоком измерени контраста интерференционной картины, причем фазовый модул тор расположен в системе формировани предметного пучка, линза размещена за регистратором голограмквл, а входное окно блока измерени контраста интерференционной карт1«ы установлено в плоскости фокусировани интерференционных полос.HOLOGRAPHIC INTERFEROMETER of real time, containing a laser, a beam splitter, object and reference beam formation systems and a hologram recorder, which is due to the fact that, in order to measure the autocorrelation function of scattered radiation, the interferometer is equipped with a phase modulator, lens and a unit for measuring the contrast of the interference pattern, the phase modulator being located in the object beam forming system, the lens is placed behind the hologramkl recorder, and the input window of the contrast measurement unit and An interference card is installed in the focusing plane of the interference fringes.
