幻象阵列被用来探测伴随扫视眼球运动的视网膜局部信号的变化的时间过程。当一个人在黑暗中扫视一个每秒闪烁120次的点光源时，幻象阵列就会出现。人们看到一个固定的闪光阵列第一个在扫视的预期终点附近离散地实现，随后的闪光逐渐接近闪烁光的实际位置。四名经过培训的观察员指出了相对于体模阵列的1 msec标记闪光（M）的感知位置，该标记闪光由两个LED（发光二极管）产生，垂直包围闪烁光。当标记物在扫视前闪烁80至0毫秒时，标记物被视为与第一次闪烁在空间上一致，并且当标记物在扫视前闪烁大于80毫秒时，标记物被视为与第一次闪烁或闪烁光的实际位置在空间上一致，分别指示轴是扫视前的和相当突然的。
Thephantom array was used to probe the time course of the shift in retinal local signs that accompanies a saccadic eye movement. The phantom array materializes when one saccades in the dark across a point light source blinking 120 times per second. One sees a stationary array of flashes—the first materializes discretely near the intended endpoint of the saccade, and subsequent flashes materialize progressively closer to the actual position of the blinking light. Four trained observers indicated the perceived location, relative to the phantom array, of a 1-msec marker flash (M) produced by two LEDs (light-emitting diodes) that vertically bracketed the blinking light. The marker was seen as spatially coincident with the first flash when it flashed 80 to 0 msec before the saccade, and was seen as spatially coincident with either the first flash or the actual position of the blinking light when it flashed mare than 80 msec before the saccade, indicating, respectively, that the shaft is presaccadic and rather abrupt.
