Description
С тест-объектом работают следующим образом .With the test object work as follows.
На светочувствительный материал, установленный в испытуемой камере 6, через объектив 5 поступает свет, отразившийс от узлов 2 плоского тест-объекта. Одновременно на светочувствительный материал поступает свет от мнимых узлов 8 тест-объекта. Мнимые узлы 8 тест-объекта образуютс за счет многократного отражени реальных узлов 2 плоского тест-объекта от зеркальных поверхностей .The photosensitive material, installed in the test chamber 6, receives light through the lens 5, reflected from the nodes 2 of the flat test object. At the same time, light from imaginary nodes 8 of the test object enters the photosensitive material. The imaginary nodes 8 of the test object are formed by repeatedly reflecting the real nodes 2 of the flat test object from the mirror surfaces.
Изображени реальных узлов, видимых в зеркале 1, вл ютс пространственными и объективно существующими независимо от фотокамеры 6, фотографирующей их. Мнимые узлы 8, видимые в зеркале /, занимают совершенно определенное положение в пространстве , определ емое рассто нием между зеркалами / и 5 и взаимным расположением узлов 2.The images of the real nodes seen in mirror 1 are spatial and objectively existing independently of the camera 6 photographing them. The imaginary nodes 8, visible in the mirror /, occupy a completely definite position in space, determined by the distance between the mirrors / and 5 and the mutual arrangement of the nodes 2.
Координатную систему пространственного тест-объекта выбирают таким образом, чтобы плоскость OXZ совпала с плоскостью зеркала Л а ось У была перпендикул рна ей.The coordinate system of the spatial test object is chosen so that the OXZ plane coincides with the plane of the mirror L and the Y axis is perpendicular to it.
Математическа зависимость, определ юща св зь координат контрольных точек, нанесенных на зер.кальную поверхность, с координатами точек пространственного тест-объекта , в зависимости от рассто ни между зеркальными поверхност ми, следующа A mathematical relationship that determines the relationship between the coordinates of control points plotted on a mirror surface and the coordinates of points in a spatial test object, depending on the distance between the mirror surfaces, is
