Abstract

This paper presents the Zerotrope, an improved version of the classic phenakistiscope and zoetrope devices. This device is used to create a new 360-degree dynamic 3D display by the inclusion of a single ultra-realistic full-color hologram. The Zerotrope is built with a zero-degree transplane hologram mounted on a disk rotating at a constant speed. When a stroboscopic lamp synchronized with the rotation illuminates this hologram, the recorded characters, arranged radially around the center of the disk, are animated as in a stop-motion movie. The operation of the Zerotrope is successful and shows the effect of a 3D display without the need for special viewing aids.

Highlights

  • Three-dimensional (3D) displays constitute an important research topic [1,2,3]

  • Inspired by the pre-movie mechanical devices history, the authors designed the FantatropeTM in 2018. It is a holographic zoetrope composed of a series of twelve ultra-realistic full-color holograms arranged in a chronological sequence and mounted on a cylindrical rotating base [6]

Summary

Introduction

Three-dimensional (3D) displays constitute an important research topic [1,2,3]. Most current approaches use the stereoscopic principle [4], which can cause visual discomfort and visual fatigue for the viewer [5]. Inspired by the pre-movie mechanical devices history, the authors designed the FantatropeTM in 2018 It is a holographic zoetrope composed of a series of twelve ultra-realistic full-color holograms arranged in a chronological sequence and mounted on a cylindrical rotating base [6]. The viewer rotates the disk by hand and views the sequence reflected in a mirror through the moving slots. This rapid succession of pictures creates an illusion of a moving image for the viewer. Modern 3D zoetropes exploit a principle similar to that of the traditional zoetrope, with three-dimensional (3D) solid models on a rotating turntable synchronized with a strobe light
