Holographic generation of panoramic 3D scenes by concave ellipsoidal mirror reflection

|
By Yusuke Sando, Yutaro Goto, Daisuke Barada
| Optica Verified
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.

Hyperboloidal mirror reflection for super-wide viewing zones in computer-generated holography

| Optica Verified
A hyperboloidal mirror can widen the spreading angle of an incident spherical wave by reflecting the spherical wave outside the hyperboloidal mirror. We propose using this geometrical reflection property to widen the viewing zone in computer-generated holography (CGH). A hyperboloidal mirror was placed after wavefront modulation by a hologram, and it reflected the wavefront radially with a wide spreading angle.

Real-time computing for a holographic 3D display based on the sparse distribution of a 3D object and requisite Fourier spectrum

Abstract In holographic three-dimensional (3D) displays, the surface structures of 3D objects are reconstructed without their internal parts.
