The present invention provides methods, systems and software for scaling optical aberration measurements of optical systems. In one embodiment, the present invention provides a method of reconstructing optical tissues of an eye. The method comprises transmitting an image through the optical tissues of the eye. Aberration data from the transmitted image is measured across the optical tissues of the eye at a first plane. A conversion algorithm is applied to the data, converting it to corrective optical power data that can be used as a basis for constructing a treatment for the eye at a second plane.

Wavefront propagation from one plane to another

Methods, software, and systems are provided for determining an ablation target shape for a treatment for an eye of a patient. Techniques include determining wavefront information from the eye of the patient with a wavefront eye refractometer, determining anterior corneal shape information from the eye with a corneal topography device, and combining the wavefront information and the anterior corneal shape information to determine the ablation target shape.

Combined wavefront and topography systems and methods

The invention disclosed is an apparatus and method for stabilizing an archery bow and reducing recoil during arrow draw and release. The apparatus comprises an adjustable arm clamp assembly; a rod; a support body for attaching the arm clamp assembly to the rod; and a mounting block for attaching the rod to an archery bow. The archery recoil stabilizer is lightweight, adjustable and relies on bracing the arm from the forearm position to restrict translational and rotational movement of the bow as well as minimize recoil impacts. It supports the arm by bracing the forearm relative to the bow, and reduces or eliminates bow hand torque, providing improved stabilization during both arrow draw and release. Additionally, this invention reduces the stress and recoil on the arm of the archer that can cause pain or injury, or can compromise the flight of the arrow and the accuracy of the shot.

Devices systems, and methods can characterize an optical surface of an object. A wavefront sensor system focuses light energy propagating from the object to form a pattern on a detector. The system maps the pattern to an array with a transform function such as a Fourier transform. The values of array correspond to characteristic locations and signals in a transform space, for example an intensity of spatial frequency signals in frequency space. The characteristic location and intensity of these signals in transform space are used to measure the optical surface. For example, a characteristic frequency of a spatial frequency intensity peak in Fourier transform space can be used to estimate the location of spots on the detector. Alternatively, the characteristics can be used to the measure sphere, cylinder and axis of a wavefront, wavefront elevation maps and point spread functions, often without locating positions of individual spots on the detector.

Methods, systems and software for determining an optical surface model for an optical tissue system using Fourier transformation algorithms. A method of reconstructing optical tissues an eye comprises transmitting an image through the optical tissues of the eye. The surface gradients from the transmitted image are measured across the optical tissues of the eye. A Fourier transform algorithm is applied to the surface gradients to reconstruct an optical surface model that corresponds to the optical tissues of the eye.

Optical surface shape determination by mapping a lenslet array spot pattern to spatial frequency space

A system for determining the shape of an object and/or a distance of the object from the system includes a first plurality of light source, a second plurality of light sources, and a detector or detector array. The first plurality of light sources are disposed about a central axis and are separated from the central axis by radial distances defining an aperture in the first plurality of light sources. The system also includes an optical system adapted to provide light from the second plurality of light sources through the aperture to the object. The system may further include a computer configured to determine the shape of the object and/or the distance of the object from the system using light from the first and second plurality of light sources that is reflected from the object and received by the detector.

A system measures a corneal topography of an eye. The system includes a group of first light sources arranged around a central axis, the group being separated from the axis by a radial distance defining an aperture in the group; a plurality of second light sources; a detector array; and an optical system adapted to provide light from the second light sources through the aperture to a cornea of an eye, and to provide images of the first light sources and images of the second light sources from the cornea, through the aperture, to the detector array. The optical system includes an optical element having a focal length, f. The second light sources are disposed to be in an optical path approximately one focal length, f, away from the optical element.

Optical devices, systems, and methods can produce and/or measure cylindrical (as well as spherical) lens shapes throughout a range of both powers and cylindrical axes. Fluid focus lenses employ electrical potentials to vary the shape of a fluid/fluid interface between two immiscible fluids having differing indices of refractions by controlling localized angles between the interface and a surrounding container wall. Spherical power, cylindrical power, and cylindrical access alignment may be varied with no moving parts (other than the fluids).
