Adaptive optics (AO) is a technique that removes the atmospheric disturbance and allows a telescope to achieve diffraction-limited imaging from the ground. This is critical in achieving the maximum S/N given in equation (1).The basic idea of AO is to first measure the amount of atmospheric disturbance, then correct for it before the light reaches the camera.

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 Optics in atmospheric propagation and adaptive systems book the distortion. It is used in astronomical telescopes and laser communication systems to remove the effects of atmospheric distortion, in microscopy, optical fabrication and in retinal imaging systems.

Short exposures freeze the atmospheric turbulence to give images of bright stars a speckled pattern.

This pattern forms the basis of speckle interferometry and is discussed further below and in Chapter 9. Many investigators have analyzed the propagation of an optical wavefront through the earth's : James B. Breckinridge. Proc.

Wave-front distortions can be mitigated, in principle, with adaptive optics, i.e., real-time wave-front control, reducing the likeliness of signal fading. However, adaptive optics technology, currently primarily used in astronomical imaging, needs to be adapted to the requirements of free-space optical communication systems and their specific Cited by: Advances in Lasers and Electro Optics.

This book is divided in four sections. The book presents several physical effects and properties of materials used in lasers and electro-optics in the first chapter and, in the three remaining chapters, applications of lasers and electro-optics in three different areas are presented.

With the increase in computing speed it is now even possible to perform all the calculations for atmospheric adaptive optics with Pentium processors, freeing adaptive optics systems from the need for dedicated signal processing cards.

This use of standard components to make an adaptive optics system shows that the technologies are reaching.

Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light.

Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves. Working in the field of atmospheric propagation and adaptive optics, he has authored seven books in adaptive optics at various levels as well as graduated a number of master's and PhD students whose research was in physical (or Fourier) optics.

This book treats the development and application of adaptive optics for industry and medicine. The contributions describe recently developed components for adaptive-optics systems such as deformable mirrors, wavefront sensors, and mirror drivers as well as complete adaptive optical systems and their applications in industry and medicine.
