    摘要: A system for mapping a three-dimensional structure includes a projecting optical system adapted to project light onto an object, a correction system adapted to compensate the light for at least one aberration in the object, an imaging system adapted to collect light scattered by the object and a wavefront sensor adapted to receive the light collected by the imaging system and to sense a wavefront of the received light. For highly aberrated structures, a number of wavefront measurements are made which are valid over different portions of the structure, and the valid wavefront data is stitched together to yield a characterization of the total structure.

    摘要: Devices, systems, and methods that facilitate optical analysis, particularly for the diagnosis and treatment of refractive errors of the eye. Embodiments of the invention may facilitate the use of multi-modal diagnostic instruments and instrument systems, making it easier to acquire and fuse data from different measurements of the eye. For example, wavefront aberrometry may be fused with corneal topography, optical coherence topography and wavefront, optical coherence topography and topography, pachymetry and wavefront, etc. While some of these different optical datasets may be obtained simultaneously, it is often difficult and/or disadvantageous to attempt to acquire the images or other data at exactly the same time. Advantageously, both patient movement between measurements (and/or during a measurement sequence) can be identified, as well as changes in the eye itself (including those induced by the measurement, such as changes in the size of the pupil, changes in pupil location, etc.).

    摘要: An optical element which controls both the phase and irradiance distribution, thereby completely specifying the E-field, of light, allowing completely arbitrary control of the light at any plane. Such an optical element includes a portion that controls the phase and a portion that controls the irradiance. The portion that controls the irradiance is an apodized irradiance mask having its transmission varying with position in a controlled fashion. This apodized irradiance mask is preferably a pattern of metal. In order to insure a smoothly varying pattern of metal with minimized diffraction effects, a very thin mask spaced from a substrate is used to provide the metal on the substrate. The apodized irradiance mask may be placed directly on the phase control portion, or may be on an opposite side of a substrate of the phase controlled portion.

    摘要: An enhanced dynamic range wavefront sensing system includes a light source disposed on a first side of an optically transmissive device, a wavefront sensor disposed on a second side of an optically transmissive device, a relay imaging system disposed between the optically transmissive device and the wavefront sensor, and means for adjusting a distance between the light source and the optically transmissive device. Beneficially, the relay imaging system includes a range-limiting aperture to insure that the wavefront sensor never goes out of range so that a feedback system can be employed to move the light source one focal length away from the optically transmissive device.

    摘要: This invention, a Purkinjenator™ optical system, is an eye-tracker and methodology for tracking Purkinje reflection images from a human eye in real-time, which allows for the XYZ position and tip/tilt of structures inside the eye to be determined in real-time. When used in combination with programmable groups of IR LED light sources, unique patterns of Purkinje reflections from internal surfaces (and corneal surfaces) can be identified. Thus, XYZ positioning and tip/tilt of internal structures can be accurately and rapidly determined. An Optical Coherence Tomography (OCT) optical system can be combined with the Purkinjenator™ optical system to provide Z-axis distance information.

    摘要: An ophthalmic error measurement system includes a projecting optical system delivering light onto a retina of an eye, a pre-correction system which compensates a light beam to be injected into the eye for aberrations in the eye, the pre-correction system being positioned in between the projecting optical system and the eye, an imaging system which collects light scattered by the retina, and a detector receiving light returned by the retina from the imaging system. Use of the pre-correction system allows the end-to-end aberrations of the ocular system to be analyzed. The use of a pre-correction system also allows use of a minimized spot size on the retina, and all of its attendant advantages.
