Phase retrieval as a means of wavefront sensing
Proceedings of International Conference on Image Processing, 2002The paper discusses how phase retrieval can be employed as a robust technique for estimating the wavefront distortion using a lenslet array. It is shown that the principal problem of phase retrieval, namely divergence is considerably reduced when the aperture is subdivided.

Acousto-optic wavefront sensing and reconstruction
Applied Optics, 2008We employ an acousto-optic cell as a tunable-pitch wavefront sensor and study its performance. The index of refraction of two cross-standing waves forms, in the near field, an adjustable array of caustics. These caustics, similar to the lenslets used for Hartmann-Shack sensing, were measured to have an extended focal relief of 200 times their pitch. We

Wavefront Sensing and the Dynamics of Tear Film
Cornea, 2007To summarize our previous studies regarding the influence of tear-film dynamics on optical quality after blinking.Sequential higher-order aberration (HOA) measurements were performed by using a wavefront sensor. During the measurements, subjects were asked to blink every 10 seconds.

Wavefront sensing and the irradiance transport equation
Applied Optics, 1990Phase retrieval has recently been experimentally demonstrated, using the irradiance transport equation. We show that this equation provides a unified description for incoherent wavefront sensing methods, bringing new insights and opening new prospects in this area.

Diagnostic use of ocular wavefront sensing
Ophthalmology Clinics of North America, 2004Wavefront sensing represents a novel diagnostic method to measure high-order aberrations. This technology has primarily been used in conjunction with excimer laser technology for performing wavefront-guided custom ablations, targeted at the correction of low- and high-order aberrations, while not inducing further high-order aberrations.Although this ...
