Description
(5) СПОСОБ ПОЛУЧЕНИЯ ИНТЕРФЕРОГРАММ (5) METHOD FOR OBTAINING INTERFEROGRAMS
1one
Изобретение относитс к оптической интерферометрии и может быть использовано в аэродинамическом эксперименте в сочетании с серийными теневыми приборами.The invention relates to optical interferometry and can be used in an aerodynamic experiment in combination with serial shadow instruments.
Известен способ получени интерферограмм фазовых объектов, включающий формирование эталонного и измерительного пучков, получение картины их интерференции и регистрацию этой картины 13Недостатком этого способа вл етс необходимость существенного увеличени реализующего его устройства при анализе объектов больших размеров.A known method for obtaining interferograms of phase objects, including the formation of reference and measuring beams, obtaining a picture of their interference and recording this pattern.
Наиболее близким по технической сущности к изобретению вл етс способ получени интерферограмм фазовых объектов, включающий формирование эталонного и измерительного пучков и регистрацию картины их интерференг ции 121.The closest in technical essence to the invention is a method for obtaining interferograms of phase objects, including the formation of reference and measuring beams and the recording of the pattern of their interference 121.
Указанный способ реализуетс в схеме интерферометра Маха-Цандера. ФАЗОВЫХ ОБЪЕКТОВThis method is implemented in a Mach-Zander interferometer scheme. PHASE OBJECTS
Недостатком известного способа вл етс возможность анализа лишь сравнительно небольших фазовых объек тов вследствие трудности формировани и транспортировки эталонного пучка без искажени волнового фронта при анализе объектов больших размеров. Кроме того, необходимо решать проблему обеспечени равенства оптических путей эталонного и измерительного The disadvantage of this method is the ability to analyze only relatively small phase objects due to the difficulty of forming and transporting the reference beam without distorting the wave front when analyzing large objects. In addition, it is necessary to solve the problem of ensuring the equality of the optical paths of the reference and measuring
10 пучков.10 bunches.
Целью изобретени вл етс увеличение возможных размеров анализируемых фазовых объектов. The aim of the invention is to increase the possible size of the analyzed phase objects.
