    • The instrument proposed has a device for stimulating the eye (20), e.g. a flashlight (58) producing an optical stimulus. The eye exposed to the stimulus or the other eye (20) of the person being examined is illuminated with infrared light from one or more sources (56). An infrared detector (62) with high time resolution receives infrared light reflected from the eye (20) and generates a signal corresponding to the intensity of this light. The change with time of this signal is measured and analysed. Disposed in the raypath of the reflected infrared light is a mirror (60) which is partly transparent to such light and which allows part of the light to fall on an infrared image sensor (CCD camera 52) with a viewing monitor (30).
    • 该设备具有以眼(20),例如刺激的手段 在闪光光源(58),用于光学刺激的形式。 受试者的刺激所述受试者,或其它眼(20)与一个或多个红外光源(56)照射。 的红外检测器(62)接收到的眼睛(20)的高时间分辨率反射的红外光,并输出未决的相应光强度信号。 被检测和评估该信号的时间过程。 在反射的红外光的光束路径致力于部分透明镜(60),所述光的一种红外线图像传感器(CCD摄像机52)用光学监视器(30)的部分可以进入。
