Источник 1 света, выполненный на импульсной лампе, через оптическую систему 2 освещает объект 4 измерения (контактные пружины). Проекция исследуемых контактов объекта измерения че- . рез другую оптическую систему 3 - щелевую диафрагму попадает на одну из светочувствительных строк ПЗС матрицы, в которой запоминается информация о положении объекта измерения, и,затем с помощью блока 6 управления передает ее на соседнюю строку, защищенную светонепроницаемой частью диафрагмы.The light source 1, made on a flash lamp, through the optical system 2 illuminates the measurement object 4 (contact springs). The projection of the studied contacts of the measurement object after another optical system 3 - the slit diaphragm hits one of the photosensitive lines of the CCD matrix, which stores information about the position of the measurement object, and then, using the control unit 6, transfers it to the next line, protected by the opaque part of the diaphragm.

Скорость переноса определяется скоростью исследуемого процесса и задается блоком 6 управления. Частота переноса равна 1 мГц, что обеспечивает достаточную надежность измерения при высокочастотном дребезге исследуемых контактов объекта измерения. С выхода ПЗС матрицы информация выходит в виде пачек импульсов, каждая из которых соответствует положению исследуемого 'Контакта в определенный момент времени. Пачки поступают на усилитель 7 и далее на устройство регистрации, осуществляющее запоминание,’ дешифрацию . и индикацию информации.The transfer rate is determined by the speed of the investigated process and is set by the control unit 6. The transfer frequency is 1 MHz, which ensures sufficient measurement reliability with high-frequency bounce of the studied contacts of the measurement object. From the output of the CCD matrix, the information comes out in the form of bursts of pulses, each of which corresponds to the position of the investigated contact at a certain point in time. The bursts go to amplifier 7 and then to the recording device, which stores, ’decryption. and indication of information.
