Изобретение огноситс к области техн1ьI ческой физики, в частности к приборам и i I устройствам дл измерени электрическогс( потенциала, и может быть использовано i при исследованиисвойств видиконных и электрофотогра||ических слоев., ,The invention is fire related to the field of technical physics, in particular, to instruments and i I devices for measuring electrical (potential, and can be used by i in studying the properties of video layers and electrophotographic layers.,,
Известно устройство дл измерени pacUi пределени электрического потендиала в электрофотографических сло х, содержащее , вибрирующий сигнальный электрод, усилив- : ; тель и регистрирующий прибор .A device is known for measuring the pacUi of the electrical potential distribution in electrophotographic layers, which contains a vibrating signal electrode that amplifies:; tel and recording device.
Однако такое устройство имеет низкую : точность измерени из-за перераспределени электрических потенциалов прл прибпи жении сигнального электрода к поверхности исследуемого образца,However, such a device has a low: measurement accuracy due to the redistribution of electric potentials when the signal electrode is attached to the surface of the sample under investigation,
Наиболее известно устройство дл изме;рени распределени электрического , 1циала, содержащее исследуемый образец, |механизм перемещени и вибрирующий элек |трод , (Соединенный с входом блока усиле- 1ни , выход которого подключен к исследу- 1емому образцу и входу регистрирующего прибора 2. The most well-known is the device for measuring the distribution of the electrical, 1-cell containing the sample under study, the moving mechanism and the vibrating electrode (connected to the input of the amplification unit, the output of which is connected to the sample under study and the input of the recording device 2.
Однако и это устройство также имеет However, this device also has
низкую точность измерений, обусловленную тем, что исследуемый образеи перемещаете он относигельво преобразующего электрода с определенной заданной скоростью,, на аа вис щей от ре ье шого распределени nt : тенциала.low measurement accuracy, due to the fact that the sample under study moves it with respect to the transforming electrode with a certain predetermined velocity, on aa hanging from the real distribution of the nt: potential.
С целью иовыщени точности измерени предлагаемое устройство снабжено последовательно , соединенными интегратором и ; (блоком сравнени напр жений, причем вход интегратора подключен кГвьгходу б/йжа уси|. лени , а выход блока I сравнени напр женийс входом механизма перемещени , .i In order to improve the measurement accuracy, the proposed device is supplied in series, connected by an integrator and; (by the voltage comparison unit, the integrator input is connected to the control unit b / ya | laziness, and the output of the voltage comparison unit I with the input of the displacement mechanism, .i
На чертеже изображена блок схема npe/v ложенного устройства.The drawing shows a block diagram of the npe / v spurious device.
Устройство содержит преобразующий виб рирующий электрод 1, подсоединенный к блоку усилени 2. Блок усилени 2 соеаи нен с Грегистрирующим прибором 3, исслепуемым образцом 4 и интегратором 5 н&Ьр жени , Выход интегратора- 5 напр жени (подключен к блоку сравнени 6 напр жений, |coe iHeHHO viy с механизмом перемещени 7The device contains a transforming vibrating electrode 1 connected to amplification unit 2. Amplification unit 2 is connected with a registering device 3, an exploded sample 4 and an integrator 5 n & V, the integrator output is 5 voltage | coe iHeHHO viy with movement mechanism 7
