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 100 Hz 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 1 KHz.We have carried out basic experiments usinga simulated eye in conjunction with experiments on OMTs and saccade measurements.The results of these experiments confirmed that such a system is sufficiently accurate.
