摘要： Disclosed herein is a method including: (i) providing a light transmissive sample including nominally parallel internal facets, which are about perpendicular to an external surface of the sample; (ii) providing an optical element having a refractive index about equal to that of the sample and including an external first surface and an external second surface acutely inclined relative thereto; (iii) positioning the second surface of the optical element adjacent to the first surface of the sample; (iv) impinging light beams on the first surface of the optical element, about normally thereto; (v) sensing light beams, which exit out of the sample following passage of the impinging light beams via the optical element, transmission thereof into the sample, reflection once off the internal facets, and exit out of the sample; and (vi) based on the sensed data, computing a deviation from parallelism between the internal facets.

摘要： Techniques are disclosed for systems and methods to provide improved ocular aberrometry recovery. An ocular aberrometry system includes a wavefront sensor configured to provide wavefront sensor data associated with an optical target monitored by the ocular aberrometry system and a logic device configured to communicate with the wavefront sensor. The logic device is configured to receive ocular aberrometry output data including at least the wavefront sensor data provided by the wavefront sensor, identify imaging artifact induced singularities in the received ocular aberrometry output data, determine corrected aberrometry output data based, at least in part, on the identified singularities and the received ocular aberrometry output data, and generate user feedback corresponding to the received ocular aberrometry output data based, at least in part, on the corrected aberrometry output data.

摘要： A method for optimization of photonic devices is disclosed. The method includes receiving a set of unconstrained latent variables; mapping the set of unconstrained latent variables to a constrained space to generate a constrained device; calculating the permittivity across each element of the constrained device; determining a permittivity-constrained width gradient based at least partially on the permittivity across each element; and optimizing the set of unconstrained latent variables by at least partially using the permittivity-constrained width gradient.

摘要： A lensmeter system may include a mobile device having a camera. The camera may capture a first image of a pattern through a lens that is separate from the camera, while the lens is in contact with a pattern. The mobile device may determine the size of the lens based on the first image and known features of the pattern. The camera may capture a second image of the pattern, while the lens is at an intermediate location between the camera and the pattern. The second image may be transformed to an ideal coordinate system, and processed determine a distortion of the pattern attributable to the lens. The mobile device may measure characteristics of the lens based on the distortion. Characteristics of the lens may include a spherical power, a cylinder power, and/or an astigmatism angle.

摘要： A process is provided for determining characteristics of a lens, the process including obtaining a captured image of a pattern through a corrective lens; transforming the captured image to an ideal coordinate system; processing the captured image to determine an overall distortion from a reference pattern to the pattern of the captured image; determining a distortion of the captured pattern attributable to the corrective lens; and measuring at least one characteristic of the corrective lens. In some embodiments, the overall distortion is determined by detecting, in the captured image, at least one captured pattern landmark; determining a transformation from at least one ideal pattern landmark to the at least one captured pattern landmark; and determining for the corrective lens, from the transformation, a spherical power measurement, a cylinder power measurement, and an astigmatism angle measurement.

摘要： More appropriate evaluation, design, and manufacture are made feasible by taking visual performances into consideration more appropriately. In order to achieve this object, in the present invention, spectacle lenses are evaluated using a visual acuity function including a factor representing physiological astigma. The physiological astigma herein means astigma in the phenomenon that an improved visual acuity is yielded when slight astigma is present in the region where the accommodation power is lower than the region indicating the range of positive relative accommodation power in which the accommodation power increases among the relative accommodation power as adaptable accommodation power in a state that convergence does not change.

摘要： A method for inspecting lenses, especially wet contact lenses provided in a volume of liquid inside a container is described. A first image of the lens at a first position in the container is obtained, the lens then being moved to a second position within the container where a second image is obtained. A computer algorithm processes the first and second images to compare features that have moved with the lens to those features that have not moved with the lens whereby lenses are rejected if a feature has moved with the lens but is not a normal feature of the lens.
