Description
Изобретение относитс к медицинской технике, а именно к устройствам дл исследовани движени глаз.The invention relates to medical technology, namely to devices for the study of eye movement.
Целью изобретени вл етс повышение точности измерени .The aim of the invention is to improve the measurement accuracy.
На чертеже представлена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устройство дл регистрации движени глаз содержит два оптико-электронных канала , каждый из которых включает источник 1 инфракрасного излучени , объектив 2, фото- приемник 3 (регистратор). Каждый оптико- электронный канал дополнительно снабжен фильтром 4 переменной плотности, причем направлени изменени плотностей оптическихThe device for detecting eye movement contains two opto-electronic channels, each of which includes a source of infrared radiation 1, a lens 2, and a photographic receiver 3 (recorder). Each optoelectronic channel is additionally equipped with a variable density filter 4, with the directions of changing the densities of the optical
фильтров взаимно перпендикул рны, д топриемник 3, вырабатывающий электричесКроме того, каждый канал .может докии сигнал, поступающий на регистратор.filters are mutually perpendicular to the receiver 3, which produces electrical. In addition, each channel can dock a signal to the recorder.
полнен диафрагмой 5 и конденсором 6. Один канал может выдел ть горизонтальную составл ющую движени глаз, другой - вертикальную .It is filled with diaphragm 5 and condenser 6. One channel can separate the horizontal component of eye movement, the other - the vertical one.
Фильтры 4 изготовл ютс из фотопленки с пере.менной плотностью затемнени . Оптико-электронные каналы креп тс на головном шлеме.Filters 4 are made from photo film with variable shading density. Opto-electronic channels are attached to the headgear.
Инфракрасное излучение, создаваемое источником 1, помещенным в фокусе объектива 2, параллельным пучком поступает на глаз. Часть излучени может быть выделена диафрагмой 5. Отраженное от роговицы глаза излучение через фильтры 4 переменной плотности и конденсор 6 падает на фокии сигнал, поступающий на регистратор.The infrared radiation generated by the source 1, placed in the focus of the lens 2, in a parallel beam enters the eye. Part of the radiation can be allocated by the diaphragm 5. The radiation reflected from the cornea through the filters 4 of variable density and the condenser 6 falls on the foxy signal arriving at the recorder.
