Description
В известных устройствах дл определени смещений линии визировани зрительной трубы при изменении фокусировки дл проверки смещени зеркала параллельно самому себе используетс автоколлимационна труба, причем точность такой проверки составл ет О 3, что снижает точность определени смещени линии визировани исследуемой трубы.In known devices, to detect the displacement of the line of sight of the telescope when the focus is changed, an autocollimation tube is used to check the mirror displacement parallel to itself, and the accuracy of such a check is O 3, which reduces the accuracy of determining the displacement of the line of sight of the test tube.
Предлагаемое устройство исключает применение автоколлимациО .ННОЙ трубы и практически обеспечивает соверщенно параллельное перемещение жидкостного зеркала в необходимом диапазоне, что упрощает конструкцию устройства и повыщает точность определени смещений.The proposed device eliminates the use of an autocollimation of the OTHER tube and practically provides perfectly parallel movement of the liquid mirror in the required range, which simplifies the design of the device and improves the accuracy of determining displacements.
На чертеже изображена схема предлагаемого устройства, содержащего объектив /, марку 2 (перекрытие нитей) и лсидкостное зеркало 3 (например, ртутное).The drawing shows a diagram of the proposed device containing the lens /, mark 2 (overlapping filaments) and lidkostnoe mirror 3 (for example, mercury).
При проведении измерени провер емую трубу устанавливают перед объективом / и последовательно фокусируют на мнимое изображение марки 2 при различных положени х жидкостного зеркала 3, параллельность перемещени поверхности которого сохран етс с больщой точностью.When measuring, the inspected pipe is installed in front of the lens / and sequentially focused on an imaginary image of mark 2 at different positions of the liquid mirror 3, the parallelism of the surface movement of which is maintained with greater accuracy.
