WebDec 1, 2024 · A family of corrective optical measures, known as adaptive optics (AO), is one remedy 1,2. ... SH sensors work well in samples that do not scatter much, says Ji. 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. [citation needed] Adaptive optics should not be confused with active optics, which works on a longer … See more Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effect of incoming wavefront distortions by deforming a mirror in order to compensate for the distortion. It is used in See more The simplest form of adaptive optics is tip–tilt correction, which corresponds to correction of the tilts of the wavefront in two dimensions (equivalent to correction of the position offsets for the image). This is performed using a rapidly moving tip–tilt mirror that … See more Ocular aberrations are distortions in the wavefront passing through the pupil of the eye. These optical aberrations diminish the quality of the image formed on the retina, sometimes … See more Besides its use for improving nighttime astronomical imaging and retinal imaging, adaptive optics technology has also been used in other settings. Adaptive optics is used for solar … See more Adaptive optics was first envisioned by Horace W. Babcock in 1953, and was also considered in science fiction, as in Poul Anderson's … See more Atmospheric seeing When light from a star or another astronomical object enters the Earth's atmosphere, atmospheric turbulence (introduced, for … See more In microscopy, adaptive optics is used to correct for sample-induced aberrations. The required wavefront correction is either measured directly using wavefront sensor or estimated by … See more
