Description

Материал, из которого изготовл етс  фоточувствительна  пластина, должен обладать пороговой фототиристорной характеристикой, т. е. он не должен реагировать на фоновую засветку, св занную с пропусканием света системой пол ризатор - магиитна  пластина (вне домена) - анализатор, но должен иметь линейную характеристику по световому иотоку , превышающему фон. В этих услови х величина выходного сигнала на клеммах 8 пропорциональна  ркости изображени  в месте расположени  домена. Продвижение домена по схеме распространени  осуидествл етс  по стандартной методике с помош,ью вращающегос  магнитного пол , приложенного в плоскости пластины 9.Введение нового блока позволило повысить точность предлагаемого устройства в 1,3-1,5 раза по сравнению с известными устройствами.The material from which the photosensitive plate is made must have a threshold photothyristor characteristic, i.e. it should not react to background illumination associated with the transmission of light by the polarizer – magical plate (outside domain) system — the analyzer, but must have a linear characteristic on the light and current exceeding the background. Under these conditions, the magnitude of the output signal at terminals 8 is proportional to the brightness of the image at the location of the domain. Promotion of the domain according to the distribution scheme is carried out according to the standard method using a rotating magnetic field applied in the plane of the plate 9. The introduction of a new unit improved the accuracy of the proposed device 1.3-1.5 times as compared with the known devices.
