Изобретение относитс  к медицинской технике .The invention relates to medical technology.

Известны устройства дл  регистрации точки фиксации взгл да, содержащие источник света дл  образовани  роговичного блика, элемент , отражающий инфракрасное излучение и регистратор положени  блика, чувствительный к инфракрасной области спектра.There are known devices for recording the point of fixation of sight, containing a light source for the formation of a corneal flare, an infrared reflecting element, and a flare position recorder sensitive to the infrared region of the spectrum.

Однако известные устройства не обеспечивают бинокул рного зрени  и не исключают зрительной помехи от засветки глаза.However, the known devices do not provide binocular vision and do not exclude visual interference from the illumination of the eye.

Целью изобретени   вл етс  устранение указанных недостатков. Это достигаетс  тем, что отражающий элемент выполнен в виде спектроделител , отражающего инфракрасное излучение в направлении центра зрачка глаза в его нейтральном положении.The aim of the invention is to eliminate these drawbacks. This is achieved by the fact that the reflecting element is designed as a spectro-divider reflecting infrared radiation in the direction of the center of the pupil of the eye in its neutral position.

Иа чертеже схематически изображено онисываемое устройство.Figure 1 is a schematic representation of the on-display device.

Устройство содержит источник I света дл  образовани  роговичного блика, отражающий элемент, выполненный в виде спектроделител  2, оптическую систему 3, регистратор 4 положени  блика и шлем 5.The device contains a source of light I for the formation of a corneal flare, a reflecting element made in the form of a spectro-divider 2, an optical system 3, a flare position recorder 4 and a helmet 5.

Спектроделитель, отражающий инфракрасное излучение и пропускающий видимый свет, устанавливают против глаза, не преп тству  бинокул рному зрению. Источник света располагают между оптической системой и щлемом . Инфракрасна  часть его отражаетс  от спектроделител  в нанравлении центра зрачка так, что -блик образуетс  в центре поверхности роговицы глаза в его нейтральном положении . Это обеспечивает симметричность перемещени  блика по роговице и линейность смещени  его изображени  в рабочем диапазоне углов поворота глаза. Изображение роговичпого блика отражаетс  тем же спектроделптелем в оптической системе и попадает на регистратор 4, . чувствительный в инфракрасной области спектра.An infrared spectrometer that transmits visible light is placed against the eye, not hindering binocular vision. The light source is placed between the optical system and the slit. The infrared part of it is reflected from the spectral divider in the direction of the center of the pupil so that the glare is formed in the center of the surface of the cornea in its neutral position. This ensures the symmetry of the movement of the flare on the cornea and the linearity of the displacement of its image in the working range of the angles of rotation of the eye. The image of the corneal flare is reflected by the same spectrophotometer in the optical system and falls on the recorder 4,. sensitive in the infrared region of the spectrum.
