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 ... WebMay 31, 2024 · Adaptive optics works by measuring the distortions in a wavefront and compensating for them with a device that corrects those errors such as a deformable mirror or a liquid crystal array. Adaptive optics should not be confused with active optics, which works on a longer timescale to correct the primary mirror geometry.
