Изобретение относитс к контрольно .измерительной технике и может быть использойано , в частности, дл измерени угловых перемещений различного вида объектов как в лабораторных, так и в промышленных услови х.The invention relates to a control measuring technique and can be used, in particular, to measure the angular displacements of various types of objects in both laboratory and industrial conditions.
Известен автокодлимадионный способ определени угловых смещений объекта, заключающийс в том, что искомую величину определ ют по величине смещени направленного и отраженного от объекта пучков света Ll.There is a known autodynamic method for determining the angular displacements of an object, which consists in the fact that the sought value is determined by the magnitude of the displacement of the light beams directed and reflected from the object Ll.
Наиболее близким к изобретению по технической сущности и достигаемому peiзyльтaтy вл етс интерференционный способ измерени угловых перемещений объекта, заключающийс в том, что раздел ют пучсрк света на несколько пучкоЁ , затем свод т их попарно в пучки и регистрируют интерференционную- картину , по кср-орой суд т о перемещении 2.The closest to the invention according to the technical essence and the achieved resolution is the interference method of measuring the angular displacements of an object, which consists in dividing the light beam into several beams, then combining them in pairs in beams and registering the interference pattern t about moving 2.
Однако высока чувствительнсють способов к вибраци м и линейным перемещени м объекта С1шжает качество и герференционной картинь и, следовательно, снижает точность измерени .However, the high sensitivity of the methods to the vibrations and linear displacements of the object S1 shrinks the quality and germinal pattern and, therefore, reduces the accuracy of the measurement.
Целью изобретевш вл етс повьпивние точности измерени за счет снижени вли ни вибраций и линейных перемещений объекта и улучщени качества интерференционной картины.The aim of the invention is to measure accuracy by reducing the influence of vibrations and linear movements of the object and improving the quality of the interference pattern.
Это достигаетс тем, что сведением пучки каждой пары направл ют навстречу эдин другому по одному и то10 му же оптическому пути.This is achieved by converging the beams of each pair towards one other along the same optical path.
На чертеже дана принципиальна сиьтическа схема, позвол юща реализовать описываемый способ.In the drawing, the principal schematic diagram is given, which allows to implement the described method.
Оптическа схема содержит неподвиж- , The optical scheme contains a fixed,
15 ный светоделитель 1, зеркала 2 и 3, св зываемые с объектом 4.15 beam splitter 1, mirrors 2 and 3, associated with object 4.
Описываемый способ осуществл етс следующим образом.The described method is carried out as follows.
Пучок 5 когерентного света раэдел кхг с помощью светоделител 1 на пучки 6 и 7, ксугорые направл ют навстречу один другому по одному и тому же оптичесA coherent light beam 5 of the rasdel khg by means of a beam splitter 1 to beams 6 and 7, which are directed towards each other along the same optical beam.
