Ground-layer wavefront reconstruction from multiple natural guide stars [PDF]
Astrophys.J.661:1332-1338,2007, 2007 Observational tests of ground layer wavefront recovery have been made in open loop using a constellation of four natural guide stars at the 1.55 m Kuiper telescope in Arizona. Such tests explore the effectiveness of wide-field seeing improvement by correction of low-lying atmospheric turbulence with ground-layer adaptive optics (GLAO).

Compressive Wavefront Sensing with Weak Values [PDF]
, 2014 We demonstrate a wavefront sensor based on the compressive sensing, single-pixel camera. Using a high-resolution spatial light modulator (SLM) as a variable waveplate, we weakly couple an optical field's transverse-position and polarization degrees of freedom.

Quantitative surface normal measurement by a wavefront camera [PDF]
, 2012 A compact wavefront camera that allows users to quantitatively measure the intensity and wavefront at a remote object plane is reported. The camera is built from a chip-scale wavefront sensor that we previously developed.

Rhythmic Calcium Events in the Lamina Propria Network of the Urinary Bladder of Rat Pups
Frontiers in Systems Neuroscience, 2017 The lamina propria contains a dense network of cells, including interstitial cells (ICs), that may play a role in bladder function by modulating communication between urothelium, nerve fibers and smooth muscle or acting as pacemakers.

High Power Laser Science and Engineering, 2023 The spatial distribution of beams with orbital angular momentum in the far field is known to be extremely sensitive to angular aberrations, such as astigmatism, coma and trefoil. This poses a challenge for conventional beam optimization strategies when a

Evolution of refractive surgeries
Muller Journal of Medical Sciences and Research, 2017 The use of surgical procedures to correct refractive errors of the eye has come a long way. The two main types are corneal procedures and intraocular procedures.

Study of a MEMS-based Shack-Hartmann wavefront sensor with adjustable pupil sampling for astronomical adaptive optics [PDF]
, 2008 We introduce a Shack-Hartmann wavefront sensor for adaptive optics that enables dynamic control of the spatial sampling of an incoming wavefront using a segmented mirror microelectrical mechanical systems (MEMS) device.

The estimation of far-field wavefront error of tilt-to-length distortion coupling in space-based gravitational wave detection [PDF]
, 2022 In space-based gravitational wave detection, the estimation of far-field wavefront error of the distorted beam is the precondition for the noise reduction. Zernike polynomials is used to describe the wavefront error of the transmitted distorted beam. The propagation of a laser beam between two telescope apertures is calculated numerically.
