Experiments are described in which the steady-state accommodation response versus stimulus curve was measured with an infrared autorefractor for high-contrast stimuli having a 100% square-wave temporal modulation of luminance in the frequency band 1-200 Hz. Slightly more accurate responses were found at frequencies approximately 50-100 Hz, i.e. above flicker fusion. The relevance of the results to practical situations in which flicker may be experienced is discussed.
本文描述了一些实验，其中使用红外自动验光仪测量了稳态调节反应与刺激曲线，该刺激曲线针对在1-200Hz频段内具有100%方波时间亮度调制的高对比度刺激。在大约50-100Hz的频率下，即高于闪烁融合频率时，发现反应略微更准确。文中还讨论了这些结果与可能会遇到闪烁的实际情况的相关性。
