Near-infrared wavefront sensing
We discuss the advantages of wavefront sensing at near-infrared (IR) wavelengths with low-noise detector technologies that have recently become available. In this paper, we consider low order sensing with laser guide star (LGS) adaptive optics (AO) and high order sensing with natural guide star (NGS) AO. We then turn to the application of near-IR sensing with the W. M. Keck Observatory (WMKO) A...
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 کاملWavefront sensing using diffractive elements.
In this Letter, we introduce a wavefront slope sensor based on a diffractive element. The diffractive element wavefront sensor (DEWS) produces four double overlapping copies of the incoming wavefront acting like a combination of shearing and pyramidal sensors. The DEWS allows a simple and fast slope estimate. The wavefront sampling can be as high as the number of pixel assigned to cover a wavef...

a T p HE PRESENCE OF OPTICAL ABERRATIONS THAT BLUR retinal images were the subject of popular lectures by Helmholtz in the 1860s, and led him to state: Now, it is not too much to say that if an optician wanted o sell me an instrument which had all these defects, I hould think myself justified in blaming his carelessness in he strongest terms and giving him back his instrument.”1 ecently, the av...
