Description
Изобретение относится к автоматике и вычислительной технике, в частности, к устройствам для преобразования изображений в элек· трические сигналы. · .The invention relates to automation and computer technology, in particular, to devices for converting images into electrical signals. ·.
Известно устройство, содержащее блок проецирования изображений, оптически связанный с блоком преобразования изображения, выполненного в вице чувствительной поверхности (1 ].A device is known comprising an image projection unit optically coupled to an image conversion unit made in a vice sensitive surface (1).
Этому устройству свойственна невысокая точность преобразования изображений.This device is characterized by low accuracy of image conversion.
Наиболее близким к изобретению относится устройство, содержащее фазовый детектор, вход которого соединен с блоком питания, блок проецирования изображений и генератор звуковых колебаний [2].Closest to the invention relates to a device containing a phase detector, the input of which is connected to a power supply, an image projection unit and a sound oscillation generator [2].
Целью изобретения является повышение точности устройства.The aim of the invention is to improve the accuracy of the device.
Достигается это тем, что оно содержит блок формирования деформационных колебаний, входы которого подключены к генератору, звуковых колебаний, к блоку питания и оптически связаны с блоком проецирования изображений, а выход соединен с одним входом фазового детектора, другой вход которого подключен к генератору звуковых колебаний, а так10 же тем, что блок формирования деформационных колебаний содержит подложку, выполненную в виде кварцевого стержня, на поверхность которой нанесены пленка из светопровоДящего полупроводника й металлические контакты.This is achieved by the fact that it contains a block of formation of deformation vibrations, the inputs of which are connected to a generator, sound vibrations, to a power supply unit and are optically coupled to an image projection unit, and the output is connected to one input of a phase detector, the other input of which is connected to a sound vibration generator, as well as the fact that the deformation vibration generation unit contains a substrate made in the form of a quartz rod, on the surface of which a film of light-conducting semiconductor and metallic contacts.
Йа чертеже представлена блок-схема устройства.The drawing shows a block diagram of a device.
Устройство включает генератор звуковых колебаний (частот) 1, блок 2 формирования деформационных колебаний, содержащий подложку 3, выполненную в виде кварцевого стержня, на верхнюю поверхность которой нанесена пленка 4 из светопроводящего полупроводника, имеющего собственную проводимость и металлические контакты 5, выполненные, например, в виде алюминиевых полосок, блок питания 6, резистор 7, фазовый детектор 8, блок 9 проецирования (оптических) изображений и звукопоглощающий блок 10.The device includes a generator of sound vibrations (frequencies) 1, a deformation vibration generation unit 2, comprising a substrate 3 made in the form of a quartz rod, on the upper surface of which a film 4 of a light-conducting semiconductor having its own conductivity and metal contacts 5, made, for example, is applied in the form of aluminum strips, a power supply 6, a resistor 7, a phase detector 8, a block 9 for projecting (optical) images and a sound-absorbing block 10.
Устройство работает следующим образом.The device operates as follows.
Блок 9 проецирует изображение на поверхность пленки 4. Генератор 1 через блок 2 обеспечивает генерирование поверхностной акустической волны, распределяющейся от бло3 724094 ка 2 к блоку 10. Разность потенциалов между металлическими контактами 5 от блока 6 при распространении поверхностной акустической волны изменяется и регистрируется на резисторе 7, откуда изменяющееся напряжение поступает на фазовый детектор 8, куда также подается напряжение опорной звуковой частоты от генератора 1.Block 9 projects an image onto the surface of the film 4. Generator 1 through block 2 generates a surface acoustic wave distributed from block 3 724094 ka 2 to block 10. The potential difference between the metal contacts 5 from block 6 during propagation of the surface acoustic wave changes and is recorded on the resistor 7 from where the changing voltage is supplied to the phase detector 8, where the voltage of the reference sound frequency from the generator 1 is also supplied.
При каждой частоте звуковых колебаний проводимость пленки, измеряемой на резисторе 7, представляет собой условие, при котором частотные последовательности Фурье являются аналогом изображения, проецируемого блоком 9 на плёнку 4. ’At each frequency of sound vibrations, the conductivity of the film, measured on resistor 7, is a condition under which the Fourier frequency sequences are analogous to the image projected by block 9 onto film 4. ’
Введение новых блоков и новых конструктивных связей позволяет существенно повысить точность устройства.The introduction of new blocks and new structural connections can significantly improve the accuracy of the device.
