Information in wavefront sensing - fundamental limits to wavefront measurement
Imaging and Applied Optics, 2013An information approach leads to a fundamental limit to the accuracy of wavefront sensors that is independent of the type of wavefront sensor which is used to investigate the performance of different sensors.

Repeatability of Ocular Wavefront Measurement
Optometry and Vision Science, 2003ABSTRACT: Purpose. To assess the repeatability of measurements of ocular aberrations using wavefront sensing in a small group of observers and to assess the potential effect of measurement error on custom corneal correction due to this variability.

A Scanning Interferometer for Wavefront Aberration Measurements
Applied Optics, 1969The fundamental Principles of Operation and of the design of a new type of lateral shearing interferometer are described. This instrument has the advantage over existing devices that no computation is required in order to derive the wavefront shape from the interferogram.

Self-calibration for transmitted wavefront measurements
Applied Optics, 2007Micro-optic components and subsystems are becoming increasingly important in optical sensors, communications, data storage, and many other diverse applications. To adequately predict the performance of the final system, it is important to understand the element's effect on the wavefront as it propagates through the system. The wavefront can be measured

Subaperture stitching for measurement of freeform wavefront
Applied Optics, 2015A method based on subaperture stitching for measurement of a freeform wavefront is proposed and applied to wavefronts calculated from the slope data acquired using a scanning Shack Hartmann sensor (SHS). The entire wavefront is divided into a number of subapertures with overlapping zones.

LADARWave Wavefront Measurement in Normal Eyes
Journal of Refractive Surgery, 2004ABSTRACT PURPOSE: We evaluated the correlation of Alcon LADARWave wavefront measurements with clinical refraction and corneal topography. METHODS: In a retrospective, non-comparative case series, 60 eyes (30 patients) of healthy individuals evaluated by preoperative examination for refractive surgery were enrolled (manifest sphere, -

Absolute calibration of a Shack-Hartmann wavefront sensor for measurements of wavefronts
Photonic Instrumentation Engineering VI, 2019A high-quality flat wave front is usually used to calibrate the Shach-Hartmann wave-front sensors. The article discusses the possibility of calibrating sensors with spherical wave fronts. Special attention is paid to the consideration of calibration in standard laboratory conditions.

Wavefront measurement with synthesizing method
SPIE Proceedings, 2000This paper discussed the test of a wavefront with large aperture using synthetic wavefront method. This method means the whole tested wavefront was divided into a limited numbers of sub-apertures and Moire fringe moving was used to measure the average slopes of wavefront on the sub-apertures and then the whole wavefront was synthesized. The paper dealt
