Description
оптичеокой оси системы. Это дюижен-ие создает элект|рома:гнитный канистор (камертонного типа 14, работающий от генератора 18. Часть оветавсхго тотака, проход ща через диафрагму 6, inocTiyinaeT на фотаприемиик 8, -где (преобразуетс в синусоидальный электрический сигнал, который через усилитель 15 .поступает на вхсид X осциллографа 17. Горизонтальна развертка осциллографа осуществл етс от генератора 18 с частотой скакировави диафрагмы .optical axis of the system. This duo creates an elec- tric: rotary canister (fork type 14, powered by generator 18. Part of the current flow through diaphragm 6, inocTiyinaeT on photopriemik 8, where (converted into a sinusoidal electrical signal through amplifier 15). enters the X-axis of the oscilloscope 17. The horizontal sweep of the oscilloscope is carried out from the generator 18 with the frequency of the jumping aperture.
Если среднее положение окаиирующей диафр .агмы 6 совпадает с плоскостью наилучшей ycTiawciBiKH, созданной иапытуемым оптичес1юи1М элементом -11, то сигнал с фотап1рие1Мника имеет частоту, раввую удвоенной частоте окаиироеани , а амплитуды этого сигнала дл 1К1рай.«их 1положеН|ИЙ диафрагмы 6 равны.
