Web25 Dec 2024 · Most strikingly, the reconstructed wavefronts show a helical structure with a smooth and continuous rotation by ∼1 wavelength, indicating a unit topological charge. In addition, the direction of wavefront twist that symbolizes the sign of the topological charge reverses from clockwise to anti-clockwise when comparing ( Figure 2 b) to ( Figure 2 d). WebWe can use interferometric methods, however these may be limited to the use of coherent light (like a laser). Shack-Hartmann wavefront sensors can work in incoherent and even …
