Ball lenses are highly polished spheres made of optically transparent homogeneous materials. A carefully controlled manufacturing process produces spheres with precise diameters and unsurpassed surface quality. Ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ease the sensitivity of translational alignment. Half-ball (hemispherical) lenses are ideal for applications such as fiber communications, endoscopy, microscopy, optical pickup devices, and laser measurement systems.

The error diffusion algorithm iterates between the pixels of the hologram plane in turn, rather than between the hologram plane and the object image plane，Without any information of the object image, only the complex amplitude hologram itself can be directly operated on it and a pure phase hologram can be calculated.

According to the amplitude distribution of the hologram plane and the reconstructed image plane, the phase information of the light field in the hologram plane can be obtained by iterating the forward and reverse light wave transmission and the restrictions imposed on the two planes.

CGH stands for computer-generated holograms (CGH). Holograms are unique in their ability to record both the intensity and phase of information.

The iterative algorithm usually starts from an approximation of the target hologram, and continuously optimizes the approximate hologram through a series of repeated operations until the reconstructed image obtained by the approximation meets certain error requirements.
