Description

(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ПАРАМЕТРОВ(54) DEVICE FOR MEASURING PARAMETERS

ВИБРАЦИЙVIBRATION

TQB 4,5 были одинаковыми, попадает излучение только от посторонних засветок.TQB 4.5 were the same, only radiation from outside illumination gets.

Сигналы с фотоприемника 4 и фоторезкстора 5 через усилители 6 и 7 поступают на блок вычитани  сигналов, на выходе которого выдел етс  сигнал, не завис щий от фоновых засветок несущий информацию о перемещении объекта.The signals from the photodetector 4 and the photoresistor 5 through amplifiers 6 and 7 are fed to a signal subtraction unit, at the output of which a signal is released that is independent of the background light and carries information about the movement of the object.

Формула изобретени Invention Formula Устройство дл  измерени  параметров вибраций по авт. св. № 352149, oтлu iaющеес  тем, что, с целью исключени  вли ни  фоновых засветок и повышени  помехоустойчивости схемы, в него введены кольцевой фоторезистор и блок вычитани  сигналов, причем фотоприемник расположен в центре кольцевого фоторезистора, выход которого через усилитель подключен к одному из входов блока вычитани  сигналов, к другому входу которого через второй усилитель подключен выход фогоприемника, а выход блока вычитани  сигналов соединен со входом детекторного каскада.Device for measuring the parameters of vibration auth. St. No. 352149, ia is due to the fact that, in order to eliminate the background illumination and increase the noise immunity of the circuit, a ring photoresistor and a signal subtraction unit are inserted in it, the photodetector being located in the center of the ring photoresistor, the output of which is connected to one of the subtractor unit inputs signals, to the other input of which, through the second amplifier, the output of the receiver unit is connected, and the output of the signal subtraction unit is connected to the input of the detector stage.
