Abstract
Устройство для измерения разрешающей способности зрения по частоте световых мельканий, содержащее кнопку испытуемого, генератор линейно изменяющегося напряжения, преобразователь напряжение-частота, источник световых импульсов, вычислитель, блок индикаторов и формирователь импульса по спаду сигнала, причем выход генератора соединен с входом преобразователя напряжение-частота, выход которого соединен с входами источника световых импульсов и вычислителя, выход вычислителя соединен с входом блока индикаторов, вход формирователя импульса по спаду сигнала соединен с выходом кнопки испытуемого, а выход - с входом вычислителя, выход кнопки испытуемого соединен также с входом генератора, отличающееся тем, что в него дополнительно введены второй преобразователь напряжение-частота и второй источник световых импульсов, причем выход второго преобразователя напряжение-частота соединен с входом второго источника световых импульсов. A device for measuring the resolution of vision by the frequency of light flickering, containing a test button, a linearly varying voltage generator, a voltage-frequency converter, a light pulse source, a calculator, an indicator unit and a pulse shaper for signal decay, the generator output being connected to the voltage-frequency converter input the output of which is connected to the inputs of the light pulse source and the calculator, the output of the calculator is connected to the input of the indicator block, the input of the pulse shaper When the signal drops, it is connected to the test button output, and the output to the computer input, the test button output is also connected to the generator input, characterized in that a second voltage-frequency converter and a second light pulse source are additionally introduced into it, and the output of the second voltage converter the frequency is connected to the input of the second source of light pulses.
