Description
9 контрэлектрод 2 через усилитель 10 соединен с амплитудным демодул тором 11, выход которого подключен к регистрирующему устройству 12.9, a counter electrode 2 through an amplifier 10 is connected to an amplitude demodulator 11, the output of which is connected to a recording device 12.
Устройство работает следующим образом.The device works as follows.
Лентопрот жный механизм прот гивает носитель 3 с равномерно зар женной поверхностью мимо ЭЛТ 1 со строго фиксироваиным зазором. Генератор пилообразного напр жени 6 воздействует на отклон ющую систему 7, и луч ЭЛТ 1 сканирует в результате поступлени сигнала с импульсного генератора 8, синхронизированного с генератором пилообразного напр жени 6.The tape mechanism pulls the carrier 3 with a uniformly charged surface past the CRT 1 with a strictly fixed gap. The sawtooth generator 6 acts on the deflection system 7, and the CRT beam 1 scans as a result of the signal from the pulse generator 8 synchronized with the sawtooth generator 6.
Высокое напр жение на электродах экрана ЭЛТ 1 иробнвает воздущный промежуток , в результате чего происходит иеренос зар да на поверхность носител . В цепи контрэлектрода формируетс импульсный сигнал, амплитуда которого пропорциональна разности потенциалов между электродами ЭЛТ 1 и участком носител . С резистора 9 сиимаетс импульсный сигнал, усиливаетс усилителем 10, подаетс на вход амплитудного демодул тора 11, выдающего огибающую импульсов, и на регистратор, фиксирующий данную информацию.The high voltage on the electrodes of the CRT 1 screen rotates the air gap, as a result of which the charge is transferred to the surface of the carrier. A pulse signal is formed in the counter electrode circuit, the amplitude of which is proportional to the potential difference between the CRT electrodes 1 and the carrier section. From resistor 9, a pulse signal is amplified, amplified by amplifier 10, fed to the input of an amplitude demodulator 11, which produces a pulse envelope, and to a recorder that captures this information.
Изменение площади носител 3 измен ет плотность зар да, нанесенного на него. В результате через резистор 9 протекаетA change in the area of the carrier 3 changes the density of the charge applied to it. As a result, through the resistor 9 flows
ток, завис щий от величины потенциала на участке носител , то есть от плотности распределени зар да по площади носител . Данный способ при достаточно простой аппаратуре позвол ет измер ть деформацию движущегос носител с большой точностью .a current depending on the magnitude of the potential in the carrier section, i.e., on the density of the charge distribution over the carrier area. With sufficiently simple equipment, this method allows one to measure the deformation of a moving carrier with great accuracy.
