当人的头部倾斜时,眼睛向相反方向转动,以使视网膜稳定在垂直方向,眼睛的这种扭力主要起源于前庭,已被很多作者所证实。以往是采用电磁技术进行测量。Vieville等利用红外图象三维实时眼动测量系统(EMIRAT)测量人眼动态反向转动,定量分析前庭视觉反射传导功能。其方法是,把一个固体元件照相机或称电荷耦合装置(CCO)放在受试者戴的头盔上进行红外摄影,然后由电子计算机作图象处理,可得到与电磁技术有同样的增益。
When a person’s head is tilted, the eye turns in the opposite direction to stabilize the retina in the vertical direction. The torsion of the eye mainly originates in the vestibule and has been confirmed by many authors. In the past is the use of electromagnetic technology to measure. Vieville and other use of infrared images of three-dimensional real-time eye movement measurement system (EMIRAT) measure the human eye dynamic reverse rotation, quantitative analysis of vestibular visual reflex conduction function. This is accomplished by placing a solid-state element camera or charge-coupled device (CCO) on a helmet worn by the subject for infrared photography and then computerized by an electronic computer to obtain the same gain as the electromagnetic technique.
