摘要

为了优化固态体积式真三维显示中的闪烁现象，研究了环境光对于显示闪烁的影响。通过傅里叶变换在频域获得环境光与成像光信号叠加后的频域能量分布，分析了环境光影响显示闪烁的原因。同时，设计完成了两组视觉感知实验并进行统计分析。结果显示，环境光的频率、最大光强及占空比对于真三维显示的闪烁程度有显著性影响，显著性差异小于0.001。其中，环境光的频率是影响显示闪烁的首要因素，环境光频率与显示刷新率相匹配是消除环境光对闪烁影响的主要途径；降低最大光强或提高占空比有助于消除闪烁。闪烁程度评价模型的评估结果与实验结果的相关系数大于0.99，研究结果对于基于层叠屏的三维显示闪烁程度优化具有积极的启发和指导作用。

Abstract

To optimize the flicker visibility in solid-state 3D volumetric display

the impact of ambient light on flicker in solid-state 3D volumetric display is studied. The frequency domain energy distribution of superposition of ambient light and imaging light in the frequency domain is obtained through Fourier transformation

and the possible causes of ambient light affecting display flicker are analyzed. Meanwhile

two visual perception experiments were designed and implemented

and the experimental data are statistically analyzed. The research result shows that the frequency

maximum intensity and duty cycle of the ambient light have significant influence on the flicker of the 3D volumetric display

and the significant difference is less than 0.001. Among all the factors involved

the frequency of ambient light is the primary factor affecting the flicker

and the matching of the ambient light frequency with the display refresh rate is the main way to eliminate the flicker; reducing the maximum light intensity or increasing the duty cycle can help to eliminate flicker. The correlation coefficient between the estimation result of the flicker degree evaluation model and the experiment result is greater than 0.99.The research results have positive implications and guidance for the optimization of 3D display flicker intensity based on cascading screen.
