the three-dimensional [3D] volume being generated by moving a two-dimensional [2D] surface, e.g. by vibrating or rotating the 2D surface

Full Title

Optical systems or apparatus for producing three-dimensional [3D] effects, e.g. stereoscopic images (in microscopes G02B21/22) > the image being built up from image elements distributed over a three-dimensional [3D] volume, e.g. voxels > the three-dimensional [3D] volume being generated by moving a two-dimensional [2D] surface, e.g. by vibrating or rotating the 2D surface
