This paper reports on the development of a new eye-tracking system for noninvasive recording of eye movements. The eye tracker uses a flying-spot laser to selectively image landmarks on the eye and, subsequently, measure horizontal, vertical, and torsional eye movements. Considerable work was required to overcome the adverse effects of specular reflection of the flying-spot from the surface of the eye onto the sensing elements of the eye tracker. These effects have been largely overcome, and the eye-tracker has been used to document eye movement abnormalities, such as abnormal torsional pulsion of saccades, in the clinical setting.
本文报道了一种用于非侵入性记录眼球运动的新型眼动追踪系统的研发情况。该眼动追踪器使用飞点激光选择性地对眼睛上的地标进行成像，随后测量水平、垂直和扭转眼球运动。为了克服飞点从眼睛表面镜面反射到眼动追踪器传感元件上的不利影响，需要进行大量工作。这些影响已基本得到克服，并且该眼动追踪器已被用于在临床环境中记录眼球运动异常情况，例如扫视时异常的扭转冲动。
