WebJan 1, 2024 · Greenwood frequency The Greenwood frequency, f G , provides the tem poral frequency at which the path-in tegrated phase errors “ change ” due to a path-dependent transverse wind speed, v w ( z ). In adaptive optics, the Greenwood frequency is the frequency or bandwidth required for optimal correction with an adaptive optics system. It depends on the transverse windspeed and the turbulence strength in the atmosphere. This can be easily understood since if the turbulence moves over the telescope opening faster, the speed at which the wavefront needs to be corrected is higher, and vice versa. There are various ways to define the Greenwood frequency, but all th…
