How do adaptive optics work

WebThe adaptive optics correction depends on having a bright point source near the field of view to provide the information on the atmospheric distortion to the system. This source can be a bright astronomical source or an artificial point source created by a laser beam. The requirement for proximity is such that the measurement of the distortion ... WebThe Inouye Solar Telescope’s team is tackling this challenge using a process called adaptive optics. This literally means the optics – in this case, mirrors – are warped to counteract the waves, turbulence and other disturbances in our atmosphere.
