The present invention relates to a deformable mirror, specifically a gimbaled deformable mirror for use with wavefront sensors, which mirror separates the tilt correction from the higher order modes (e.g. defocus, spherical, astigmatism, and coma at higher order aberrations, up to the limits of a particular mirror design) in order to use all of the available mirror deformation stroke for correcting the higher order modes. The separation is done by placing the deformable mirror in a gimbaled structure, so that the deformable mirror can be tilted in two independent, orthogonal axes.

Methods and compositions are disclosed for quickly creating durable surface marks and/or decorations on substrates including metal, glass, ceramic, porcelain, natural and engineered stone, as well as plastics, polymer composites and other organic materials with color, high resolution and high contrast using inkjet technology and laser, NIR diode or UV LED energy. The improved methods and compositions are based on established and emerging sub-micron and nanoparticle technology. Most properties of nanoparticles are size dependent and do not become apparent until the particle size has been reduced to the nanometer scale. Examples of such properties include increased specific surface area, facilitating the absorption and/or scattering of visible light and laser, NIR diode or UV LED energy and the decreased melting point of such materials when their particle size is reduced to the nanometer scale. Improved results such as smoothness and durability are obtained by using nanoparticles of silica, pigments and other materials in such marking processes.

High contrast surface marking using nanoparticle materials

A new technique which uses a pump-probe methodology to place a molecule into one or more excited rotational and/or vibrational states. By evaluating spectral changes due to at least one discrete frequency of pump photons a multi-dimensional characterization of the molecule's excited state energy level results. This multi-dimensional characterization typically involves evaluating the changes between excited and unexcited state measurements. The differential nature of the evaluation makes the technique self-referencing and solves problems common to many spectroscopic techniques. The multi-dimensionality of the technique provides high specificity and immunity to interferents. The preferred embodiments involve excitation by using photons suited to pumping the rotational states and evaluating the effects by probing the energy levels of one of more vibrational states. The technique is capable of detecting bulk and trace concentrations of a molecule in gas, liquid and solid phases, both in pure form and in the presence of other molecules.

The device and method of the present invention are useful for determining the characteristics of an infrared wavefront. The present invention involves positioning a beam of light containing the infrared wavefront to be characterized onto a distorted grating, using the grating to produce a plurality of images, determining the infrared wavefront from the plurality of images and analyzing the infrared wavefront for features that characterize the infrared wavefront.

A system, for determining characteristics of a beam wavefront and reshaping such wavefront, including: apparatus for sampling the wavefront curvature and generating outputs; apparatus for reshaping the wavefront; and apparatus for receiving the outputs, proportioning the outputs to match the inputs need to drive controls for the reshaping apparatus, and sending the proportioned outputs to the reshaping apparatus.

Apparatus for determining whether cornea (vitro or in vivo) has been modified (surgically or otherwise). The method includes the steps of: passing a beam of collimated light through the cornea to produce a distorted wavefront; determining the characteristics of the distorted wavefront; and analyzing the distorted wavefront for characteristics that identify the presence of a modification. The analysis of the distorted wavefront can be for the presence of higher order aberrations, or Gausian characteristics which are indicative of modifications. The method includes the steps of providing an optical system that has a pupil plane and an image plane at a detector; positioning the cornea in the pupil plane; passing a collimated beam of light through the cornea to produce at least two images in the image plane; determining the characteristics of the distorted wavefront; and analyzing the distorted wavefront for characteristics that identify the presence of a modification.

A ophthalmic aberrometer uses a wavefront sensor aligned with an eye under examination through an optical path and a light source for introducing a light beam into the eye via the optical path, wherein the optical path has a reference through which the light beam passes before passing to an eye retina to form a reference spot on the retina, a focus dynamic range extender, and an astigmatism dynamic range extender positioned in the optical path between the reference and an eye under examination. The wavefront sensor is positioned to receive a wavefront reflected from the eye retina via the optical path.

Apparatus for determining if a cornea (whether in vitro or in vivo) has been modified (either surgically or otherwise). The method includes the steps of: passing a beam of collimated light a (either coherent or incoherent) through the cornea to produce a distorted wavefront; determining the characteristics of the distorted wavefront; and analyzing the distorted wavefront for characteristics that identify the presence of a modification. The analysis of the distorted wavefront can be for the presence of higher order aberrations, or Gausian characteristics which are indicative of modifications. More particularly, the method includes the steps of providing an optical system that has a pupil plane and an image plane at a detector; positioning the cornea in the pupil plane; passing a collimated beam of light through the cornea to produce at least two images in the image plane; determining the characteristics of the distorted wavefront; and analyzing the distorted wavefront for characteristics that identify the presence of a modification. The apparatus includes: a source of collimated light: an optical system including a distorted grating and an imaging lens (which have a pupil plane, first and second virtual planes, and an image plane); structure for positioning the cornea in the pupil plane; and a computer. The structure for positioning the cornea (which is immersed in a suitable storage fluid) includes first and second plano/plano lenses. The first and second plano lens, which are substantially and perpendicular to and centered with respect to the axis, have less than &#x3bb;/10 total distortions.
