Latest Patents
Qidong Lin holds a patent for a method and apparatus for measuring the topological charge of partially coherent fractional vortex beams. This patent describes a process where a to-be-measured partially coherent fractional vortex beam passes through a scattering object. An optimization algorithm is employed to minimize the error between measurable information and the to-be-measured information. The main electric field mode and weight of the fractional vortex beam are reconstructed using a multimode stacked diffraction algorithm. The cross-spectral density function of the partially coherent fractional vortex beam is calculated, allowing for the reconstruction of a cross-spectral density of the optical field. This process yields complete information, including light intensity, electric field association, and phase. Ultimately, reverse transmission calculations are performed to obtain a source field vortex phase distribution, enabling accurate topological charge measurement under low coherence conditions.
