Just like taking photos on Earth, astronomers face many distortion issues when it comes to taking images. The solution to this problem is a technology called adaptive optics (often called AO), originally used to improve the performance of optical systems on ground-based telescopes. [1] Adaptive optics consist of computer-controlled reshapeable mirrors. These mirrors repair distortion caused by turbulence in Earth's atmosphere. This ensures that the images obtained are of equal quality to those taken from space, with the best image so far being twice as sharp as a Hubble telescope image taken in Chile by the Magellan-Clay telescope. [2] Adaptive optics has medical benefits as well as astronomical benefits and is used in research and retinal imaging. Adaptive optics eliminates ocular aberrations, which are distortions in images of objects caused when light rays do not obey the laws that describe the perfect optical system on the retina. However, the eye is far from being a perfect optical system since it is not perfectly centered on its axis and is not a fixed optical instrument. The eye has many natural adaptations that reduce aberrations, so they are not distracting or noticeable for everyday vision. Adaptive optics has many positive interactions with economic and ethical factors due to the cheap construction price compared to alternative options and little concern for any harm actually done by the technology. This is a beneficial technology that has developed valuable uses outside of astronomy that may lead to further uses in the future. Adaptive optics is cost-effective in many ways.
