Large dynamic range Shack-Hartmann wavefront sensor based on adaptive spot matching

Light: Advanced Manufacturing
The Shack-Hartmann wavefront sensor (SHWS) is widely used for high-speed, precise, and stable wavefront measurements. However, conventional SHWSs encounter a limitation in that the focused spot from each microlens is restricted to a single microlens ...
