High-speed, minute eye movements such as ocular microtremors (OMTs), flicks and saccades contain important information about the health of the subject. Since OMTs have a frequency as high as 100Hz and minute angular displacement as low as 0.01 degree, measuring the speed and position of OMTs with adequate accuracy under non-contact conditions in the long-term is difficult. To measure a living sample stably and reliably, we have developed a novel system for measuring eye movement by combining an intelligent vision system and the corneal reflex method. The intelligent vision system has both high-speed and real-time parallel image processing capabilities, which measure to a high level of precision at 1KHz. We have carried out basic experiments using a simulated eye in conjunction with experiments on OMTs and saccade measurements. The results of these experiments confirmed that such a system is sufficiently accurate.
