s can be used in the following disciplines for image enhancement:


Vision science

Diagnosing illnesses of the eye may require high resolution images of the retina. Images taken using conventional instruments may be too poor in quality due to aberrations introduced by the eye itself. Adaptive optics offers a technique for restoring the image quality. In addition, adaptive optics may be used to create a vision simulator.


Astronomy

Turbulence introduced by the atmosphere degrades images taken using telescopes. Using adaptive optics recovers much of the information that is lost.N. Miura, "Solar Adaptive Optics System and Observations at the Hida Observatory," in Imaging Systems Applications , OSA Technical Digest (CD) (Optical Society of America, 2011), paper JWA26.
/ref> As a result, it is possible to increase the number of scientific observations.


Microscopy

AO systems can correct for the sample aberration but also for the microscope and spherical aberration introduced by index mismatch. If not corrected, these aberrations reduce the resolution of the microscope.


Defense and Space

Turbulence introduced by the atmosphere degrades performances of numerous applications like: satellite imaging, advanced imaging systems,
Free Space Optical communication Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. "Free space" means air, outer space, vacuum, or ...
and laser weapon. Deformable mirror technology enables an optimal compensation of this effect.


Laser and Physics

Laser beam shaping is showing a high increase of performance in numerous applications in physics like: * Atomic trapping * Light matter interaction at the atomic level for fundamental physics * Microelectronics mask correction * Laser cutting * Quantum computing * Free form metrology
