SAN DIEGO — Wavefront technology using a Hartmann-Shack system can be validated by conventional clinical measures, at least for lower order aberrations, according to Steven C. Schallhorn, MD.

Today, several types of wavefront sensor are commercially available: the most popular being the Shack-Hartmann; curvature sensors; and multilateral shearing interferometers. Such sensors can be found ...

Eye examinations at the opticians could become more accurate and much less subjective with a wavefront sensing system. Based on a Shack-Hartmann wavefront sensor, which detects the "ripples" of light ...

In a study conducted at the University of Rochester by Dr. MacRae and associates (presented at Association for Research in Vision and Ophthalmology in May 2001), a Shack-Hartmann wavefront sensor ...

That system could comprise "a wavefront sensor such as a Shack- Hartmann wavefront sensor, Tscherning sensor, or a ray tracing sensor," which "may be used to measure refractive errors in a user's ...

Among these, the Shack–Hartmann sensor is widely employed; it divides the incoming wavefront into subapertures, enabling the determination of local aberrations through spot centroid analysis.
