(54) ТЕЛЕВИЗИОННОЕ УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ПОПЕРЕЧНЫХ РАЗМЕРОВ ОБЪЕКТОВ(54) TELEVISION DEVICE FOR MEASURING TRANSVERSE SIZES OF OBJECTS
функцию Т в сигнал, измен ющийс T function in the signal changing
в со- ответствии с новой функцией f. здесь т линейна развертывающа функци , реализуема блоком развертки 2 луча, f, - функци , получаема на выходе преобразовател 7 при подаче на его вход функции f Этот сигнал поступает на дополнительный блок развертки 8, который поворачивает зеркало 9 в пределах угла -р , причем характер функции f, выбран таким, чтоin accordance with the new function f. here t is a linear sweep function implemented by the scanner 2 of the beam, f, is the function obtained at the output of the converter 7 when the function f is fed to its input. This signal goes to the additional scanner 8, which rotates the mirror 9 within the angle -p, and function f, is chosen such that
точка падени луча и поле зрени фотоприемника 4 остаютс непрерывно совмещенными в плоскости экрана во всем диапазоне измерени . В момент перехода луча через верхний край объекта 11 световой сигнал, поступающий на фотоприемник 4, перекрываетс , и при этом также исчезает управл ющий сигнал на входе счетчика 6. Последний открываетс и начинает счет импульсов, поступающих с цифрового датчика 5, до момента по влени луча иэ-за нижнего кра объекта 11. По числу импульсов, зарегистрированных счетИthe point of incidence of the beam and the field of view of the photodetector 4 remain continuously aligned in the plane of the screen in the entire measurement range. At the moment when the beam passes through the upper edge of the object 11, the light signal arriving at the photodetector 4 overlaps, and the control signal at the input of counter 6 also disappears. The latter opens and starts counting the pulses from the digital sensor 5 until the beam appears and for the bottom edge of the object 11. According to the number of pulses registered by the account
чиком 6, определ етс измер емый размер объекта 11.6, the measured size of the object 11 is determined.
