为了证明眼球运动对正弦波对比度阈值有深远的影响，作者使用了一种稳定视网膜图像的新方法，其中来自眼睛的浦肯野反射移动了 CRT 屏幕上显示的刺激图案。这种补偿运动的校准非常关键；大于 1% 的增益误差可能会导致严重的不稳定。在最佳条件下，图像稳定功能可将拍摄对象的对比度阈值提高约 20 倍；它还会产生分辨率大于 12 c/deg 的残像。这些结果与其他方法获得的结果相比毫不逊色。
To demonstrate that eye movements have profound effects on the sine-wave contrast threshold, the author uses a new method of stabilizing the retinal image, in which the Purkinje reflections from the eye move the stimulus pattern displayed on a CRT screen. Calibration of this compensatory motion is very critical; a gain error greater than 1% may produce significant destablization. Under optimum conditions, image stabilization elevates the subject's contrast threshold by a factor of about 20; it also produces after-images with resolution greater than 12 c/deg. These results compare favorably with those obtained by other methods.
