We investigated the frequency response of the accommodative system (0.05-1 Hz) using three stimuli: defocus blur, the effects of the chromatic aberration of the eye, and changing target size. A high-speed infrared optometer monitored accommodation while the subject viewed a target in a Badal optometer. Blur was provided by moving the target sinusoidally towards and away from the subject (1-3 D) and the size of the target was varied at the same frequency. Chromatic aberration was controlled by using either monochromatic (590 nm) or white light (3300 K). Gain and phase plots changed systematically as we varied the number of stimuli presented together. This suggests that besides defocus blur both chromatic aberration and changing size are involved in accommodative control.
我们使用三种刺激来研究调节系统的频率响应（0.05 - 1赫兹）：散焦模糊、眼睛色差的影响以及目标大小的变化。当受试者在巴德尔验光仪中观察目标时，一台高速红外验光仪监测调节情况。通过将目标以正弦方式移向和远离受试者（1 - 3屈光度）来产生模糊，并且目标大小以相同频率变化。通过使用单色光（590纳米）或白光（3300开尔文）来控制色差。当我们改变同时呈现的刺激数量时，增益和相位图会系统地变化。这表明除了散焦模糊外，色差和大小变化都参与了调节控制。
