本文介绍了一种用于分析由头部作正弦转动而诱发视动眼震的算法,它可用于分析从0.05Hz到1Hz之间正弦前庭刺激所引起的眼震,采集眼动及头部运动速度信号,累积眼动位置与前庭动眼反射通路的增益与相位。该算法与以往的算法不同,以往的算法主要是基于下列两点:①选择眼动的速度,即采用眼震信号的斜率作为快、慢相的分类;②采用快相之间的慢相号的多项式外推法以获得慢相位置的重建。而在新的算法中,我们首先假设前庭-动眼对头部正弦转动的反应也是正弦形式,其反应
This paper presents an algorithm for the analysis of ocular movements induced by a sinusoidal rotation of the head that can be used to analyze nystagmus caused by sinusoidal vestibular stimulation from 0.05 Hz to 1 Hz and to acquire ocular and head movements Velocity signal, cumulative ophthalmic position and the gain and phase of the vestibular ocular reflex pathway. The algorithm is different from the previous algorithm, the previous algorithm is mainly based on the following two points: ① select the speed of eye movement, that is, using the slope of nystagmus as the classification of fast and slow phase; ② the phase difference between the fast phase Polynomial extrapolation to obtain slow-phase reconstruction. In the new algorithm, we first assume that the response of the vestibule-eye to the sinusoidal rotation of the head is also sinusoidal and its response
