Abstract

Because holography can reconstruct the wavefront of the light emitted from an object, eyes might focus on holographically generated three-dimensional (3D) images. Therefore, eye accommodation is considered to function properly for holographic 3D images. However, the measurement of the accommodation responses to 3D images generated by electronic holographic displays have not been reported, because their viewing zone angle and screen size are limited and the observation of the reconstructed 3D images with both eyes is difficult. In the recent study, we have developed a horizontally scanning holographic display that enables the increase of both horizontal viewing zone angle and screen size. The reconstructed images can be observed with both eyes. In this study, we measured the accommodation responses to the 3D images generated by the horizontally scanning holographic display. We found that the accommodation responses to the 3D images were similar to the responses to real objects.
