Description

зившись от зеркал, соответственно, 10, 11, фокусируютс  объективом 12 в плоскость сетки 13, где формируютс , два автоколлимационных изображени  шкалы и индекса, которые проектируютс  объективом 18 на экран 19. Если при измерении происходит смещение измер емого издели , например в направлении А, то автоколлимационные изображени  шкалы и индекса перемещаютс  совместно, рассто ние между ними не измен етс , и, следовательно , погрешности отсчета не происходит . Предварительно, перед началом измерений устройство юстируетс  по эталонному образцу .Living from the mirrors, respectively, 10, 11, are focused by the lens 12 into the plane of the grid 13, where two autocollimation images of the scale and index are formed, which are projected by the lens 18 to the screen 19. If the measured item is shifted, for example, then the autocollimation images of the scale and the index are moved together, the distance between them does not change, and, therefore, no reference error occurs. Previously, before starting measurements, the device is aligned with a reference sample.
