Vergence and accommodation responses of human vision are very important factors when a 3D image is observed, and a vergence-accommodation conflict (VAC) causes perceptual distortion, visual discomfort, and fatigue for an observer. Theoretically, a hologram is expected to provide a 3D image without such a conflict. In this article, natural focusing was verified by human accommodation response (A-R) measurement during on-axis analog reflection Denisyuk hologram observation. The A-R of a group of participants were measured for a real marker and its Denisyuk hologram at various visualization distances using an Nvision K5001 autorefractor. The experimental results statistically confirmed the equivalence of the responses to the Denisyuk hologram and its real counterpart, as well as the absence of a VAC.

在查看同轴模拟反射全息图时调节反应的验证

观察3D图像时，人类视觉的发散和适应反应是非常重要的因素，发散与适应冲突（VAC）会导致观察者感知扭曲，视觉不适和疲劳。从理论上讲，全息图有望提供3D图像而不会产生这种冲突。在本文中，通过在轴模拟反射Denisyuk全息图观察过程中的人类适应性响应（AR）测量来验证自然聚焦。使用Nvision K5001自动折射仪，在不同的可视化距离下测量了一组参与者的AR，以获取真实的标记及其Denisyuk全息图。实验结果从统计学上证实了对Denisyuk全息图及其真实对应物的响应是等效的，并且不存在VAC。
