摘要： The invention is generally directed to the field of image processing, and more particularly to a method and an apparatus for determining a wavefront of an object, in particular a human eye. The invention discloses a method and an apparatus for real-time wavefront sensing of an optical system utilizing two different algorithms for detecting centroids of a centroid image as provided by a Hartmann-Shack wavefront sensor. A first algorithm detects an initial position of all centroids and a second algorithm detects incremental changes of all centroids detected by said first algorithm.

摘要： An improved wavefront sensor is provided that enhances the initial focus and precision of imaged spots used to determine the monochromatic wave aberrations of the eye. The wavefront sensor includes an adjustment camera that is independent of a lenslet camera. A laser in a lower power mode is projected onto the retina of the eye and is brought into more precise or sharp focus by a control system employing data from the adjustment camera, which aids in focusing the imaged spots. “Trombone”-type optics are used to adjust the focus of the light projected onto the retina and the imaged spots onto a sensor. The laser has a higher power mode used when acquiring data of the imaged spots from the sensor.

摘要： A selectively marked contact lens having, in one aspect, marks in an optical zone region on a surface thereof and, in another aspect, different marks outside an optical zone region of the lens, for an in-vivo lens. With the lens in-vivo, the subject's eye is illuminated and the lens is imaged. A fast algorithm is used to determine the mark coordinates in relation to a measured pupil coordinate to determine position and/or orientation of the contact lens. A wavefront aberration measurement can also be obtained simultaneously with the contact lens position measurement, as well as pupil size. A fast algorithm provides for online measurements; i.e., at a repetition rate of 10 Hz or greater, over a selected time interval. Blinking periods are determined and anomalous lens position and/or wavefront information is discarded. A most frequently occurring wavefront and/or contact lens position/orientation is determined over the selected time interval.

摘要： A topographical parameter measuring device and method utilizes a technique based on wave front reconstruction according to, e.g., Hartmann-Shack principles. The device includes a planar illuminator comprising a known array of illumination sources for projecting a light spot pattern onto a target surface. A CCD camera detects the positions of the reflected image spots in a manner similar to that in a Hartmann-Shack wave front sensor. The displacements of the light spots from reference coordinates are indicative of the slope of the surface at the plurality of sample points. A computational component is used to fit the slope data of a reference surface and the target surface to a polynomial, for example, a Zernike polynomial. The polynomial, properly weighted with the calculated coefficients, provides a continuous mapping of the elevation of the target surface. Based on the elevation data, all other topographical parameters including axial curvature, dioptric power, sphere, cylinder and others can be computed and displayed.
