Holographic generation of panoramic 3D scenes by concave ellipsoidal mirror reflection
None:
Conventional holographic three-dimensional (3D) displays have a limited ability to enlarge their field of view (FOV) and cannot reconstruct panoramic 3D scenes. This paper proposes a method to overcome this limitation by using a concave ellipsoidal mirror. The concave ellipsoidal mirror has two focal points and can converge wavefronts from its entire circumference to one focal point. Thus, a viewer located at the focal point can capture wavefronts in all directions, thereby achieving an omnidirectional FOV. To validate the proposed concept, we developed a prototype time-division system and demonstrated panoramic 3D scene generation with an FOV exceeding 270∘, far beyond the limited FOV of conventional holographic 3D displays.
