| 41. | It has further been combined with adaptive optics technology to provide sharper images of the retina.
|
| 42. | Next month, a high-tech adaptive optics mirror will be installed that should eliminate practically any atmospheric distortion.
|
| 43. | But in space, or if adaptive optics are used, then reaching the diffraction limit is sometimes possible.
|
| 44. | Another major limitation is the small field of view over which the adaptive optics correction is good.
|
| 45. | Their work is overseen by the Center for Adaptive Optics at the University of California, Santa Cruz.
|
| 46. | In some cases, they may be able to match or beat Hubble in resolution by using adaptive optics.
|
| 47. | Common methods for controlling this include collimation, adaptive optics or the use of a constant beam length axis.
|
| 48. | Specifically, coronagraphs and extreme adaptive optics.
|
| 49. | A bright star acts as a beacon that adaptive optics uses to measure the roiling of the atmosphere.
|
| 50. | Even more advanced controls, called adaptive optics, are being developed to compensate for atmospheric turbulence in telescope images.
