Achieving Diffraction-Limited Visible Imaging with a Large Aperture: Recent Breakthrough
Recent advances in technology have resulted in a breakthrough for visible imaging - diffraction-limited imaging with a large aperture telescope. Using a combination of adaptive optics and integral field spectrographs, astronomers have been able to achieve near-diffraction-limited images with a large telescope. This means that images taken with a large telescope can now be seen with a much greater level of detail than ever before. This new capability opens up a range of potential applications, such as being able to see faint objects that were previously too faint to be seen. It also means that a single large telescope can now be used to capture images of galaxies and other distant objects that would previously have required multiple smaller telescopes.
