Principles of Wavefront Sensing and Reconstruction
نویسنده
چکیده
A variety of approaches to wavefront sensing and reconstruction are surveyed as they are used in adaptive optics and related applications. These include the Gerchberg-Saxton algorithm; shearing interferometry; and Shack-Hartmann, curvature, and pyramid wavefront sensing. Emphasis is placed on the relevant optics and mathematics, which are developed in some detail for Shack-Hartmann and curvature sensing (currently the two most widely-used approaches) and also to a lesser extent for pyramid sensing. Examples are given throughout.

Wavefront sensing and reconstruction from gradient and Laplacian data measured with a Hartmann-Shack sensor.
A new wavefront sensing and reconstruction technique is presented. It is possible to measure Laplacian and gradient information of a wavefront with a Hartmann-Shack setup. By simultaneously using the Laplacian and gradient data we reconstruct the wavefront by sequentially solving two partial differential equations.
متن کاملCompressed wavefront sensing.
We report on an algorithm for fast wavefront sensing that incorporates sparse representation for the first time in practice. The partial derivatives of optical wavefronts were sampled sparsely with a Shack-Hartman wavefront sensor (SHWFS) by randomly subsampling the original SHWFS data to as little as 5%. Reconstruction was performed by a sparse representation algorithm that utilized the Zernik...
متن کاملComparison of Phase Diversity and Curvature Wavefront Sensing
We compare phase diversity and curvature wavefront sensing. Besides having completely different reconstruction algorithms, the two methods measure data in different domains: phase diversity very near to the focal plane, and curvature wavefront sensing far from the focal plane in quasi-pupil planes, which enable real-time computation of the wavefront using analog techniques. By using information...

Laser sensing has been applied in various underwater applications, ranging from underwater detection to laser underwater communications. However, there are several great challenges when profiling underwater turbulence effects. Underwater detection is greatly affected by the turbulence effect, where the acquired image suffers excessive noise, blurring, and deformation. In this paper, we propose ...
متن کاملNew methods and techniques for sensing the wave aberrations of human eyes.
During the past decade, there has been a remarkable expansion of the application of wavefront-related technologies to the human eye. The ability to measure the wavefront aberrations (WA) of an individual eye has greatly improved our understanding on the optical properties of the human eye. The development of wavefront sensors has further generated an intensive effort to revise methods to correc...
