Description
ют углы 180°, а пары 1-4, 1-6, 2-4, 2- 5, 3-5, 3-6 - углы 90°.The corners are 180 °, and the pairs 1–4, 1–6, 2–4, 2–5, 3–5, 3–6 are the corners 90 °.
Фиксирование угла поворота подвижной платформы 8 относительно неподвижной платформы 9 и выключение электропривода 10 через каждые 120° осуществл етс фиксирующим устройством 11. Безлюфтовое соединение, плавный, легкий и точный поворот платформ обеспечиваютс насыпным шарикоподщипником 12.The fixed angle of rotation of the movable platform 8 relative to the fixed platform 9 and the switching off of the electric drive 10 every 120 ° is carried out by the locking device 11. The backlash-free connection, smooth, easy and precise rotation of the platforms is provided by the bulk bearing 12.
Прибор, имеющий три фиксированных положени подвижной платформы относительно неподвижной, первое из которых соответствует углу 180° между ос ми детекторов 1-4, работает следующим образом.An instrument having three fixed positions of a mobile platform with respect to a fixed one, the first of which corresponds to an angle of 180 ° between the axes of the detectors 1-4, works as follows.
При повороте подвижной платформы на угол 120° углы между ос ми каждой пары, состо щей из подвижного и неподвижного детекторов, измен ютс с 90° на 180° и наоборот . То же происходит при повороте платформы на угол 240°. Таким образом, за один оборот платформы дл каждой пары , состо щей из подвижного и неподвижного детектора, углы между их ос ми дважды составл ют угол 90° и один раз угол 180°.When the movable platform rotates at an angle of 120 °, the angles between the axes of each pair, consisting of movable and fixed detectors, change from 90 ° to 180 ° and vice versa. The same happens when the platform rotates at an angle of 240 °. Thus, for one revolution of the platform for each pair, consisting of a movable and fixed detector, the angles between their axes make twice the angle of 90 ° and once the angle of 180 °.
Эффективность измерений при этом превосходит эффективность, обеспечиваемую одной парой детекторов, дл угла 90° - в 18 раз и дл угла 180° - в 9 раз. Поскольку в любом из трех фиксированных (рабочих ) положений общее расположение деталей прибора остаетс неизменным, услови рассе ни дерного излучени одинаковы . Так как измерени под углами 90° иAt the same time, the measurement efficiency exceeds the efficiency provided by one pair of detectors, for an angle of 90 ° - by 18 times and for an angle of 180 ° - by 9 times. Since in any of the three fixed (working) positions the overall location of the instrument parts remains unchanged, the scattering radiation conditions are the same. Since measurements are at 90 ° angles and
180° осуществл ютс одной и той же парой детекторов, исключаютс ошибки, обусловленные их неидентичностью.180 ° are carried out by the same pair of detectors, errors due to their non-identity are eliminated.
