Abstract
A phantom array can be observed when there are saccadic eye movements across a time-modulated light source. In this study, the highest frequency limit of the phantom array effect that can be observed was investigated using an LED light source by estimating the participant’s threshold frequency for the visibility of the phantom array effect using the weighted up-down method. A high luminance, narrow slit, warm white LED, and long saccadic eye movement range were used as the experimental stimuli and conditions. The mean threshold frequency for young adults was approximately 10 kHz under the proposed experimental conditions. The phantom array effect was observed even above 15 kHz in the high threshold frequency group when we divided participants into three groups according to the threshold frequency. In addition, the high threshold frequency group showed a higher eye movement speed than the other groups.
