摘要： In certain embodiments, an ophthalmic system for visualizing an interior of an eye includes an illumination system and a visualization system. The illumination system illuminates the interior of the eye. The illumination system includes an annular illuminator that directs annular illumination, which has an illumination axis, towards the interior of the eye. The visualization system provides an image of the interior of the eye. The visualization system comprises visualization optical elements, which include an objective lens and oculars. The objective lens receives light reflected from the interior of the eye. The oculars, which have an ocular axis, transmit the reflected light to yield an image of the interior of the eye. In other embodiments, the illumination system comprises a multi-beam illuminator that directs multiple illumination beams towards the interior of the eye.

摘要： Systems and methods for biometric authentication in ophthalmic devices are provided. In one embodiment, a system includes: an ophthalmic diagnostic device configured to obtain diagnostic measurements of a patient's eye, the patient's eye including an iris and a cornea; an imaging device configured to capture an image of the iris; an optical sensor integrated with the imaging module and configured to detect a position of the iris with respect to the optical sensor; and a computing device in communication with the ophthalmic diagnostic device, imaging device, and the optical sensor. The computing device may be configured to: determine, based on the image of the iris and the position of the iris, whether the iris matches a known patient's iris; and perform a diagnostic measurement of the patient's eye based on the determining.

摘要： The invention relates to an apparatus compatible with the eye-nose-cheek region, which can be integrated into indirect lenses, prevents the breath from escaping over the mask and reaching the lens by closing the area between the mask and the eye, to prevent fogging that occurs on the lens due to the patient's use of a mask and hinders the examination during examination with indirect lenses in ophthalmology.

摘要： The present invention describes systems and method for the detection, diagnosis and monitoring of cognitive impairment and Alzheimer's disease. In one example, an integrated system comprising a full-field Fourier domain optical coherence tomography and an image mapping spectrometry is used for generating spectrally resolved volumetric images at wavelengths that show difference in spectral signatures of normal cells compared to spectral signatures of amyloid beta and pTau deposits, and also image inner retinal layers where amyloid beta and pTau deposits may aggregate.

摘要： This computer-implemented method allows assessing the shear elasticity modulus of a flexible tube, such as a blood vessel. In the field of medicine, this allows assessing whether a blood vessel is at risk of breakage or tearing. In the case of an artificial tube to be implanted in a patient's body, this allows verifying that this tube is compatible with the patient's body. The method includes the following further steps: a) obtaining (1002) a first dataset relating to spatiotemporal deformations of the tube; b) detecting and storing (1004) a wall inner surface of the tube and its diameter (D); c) identifying (1006) a number of transverse sections (Sij) of the tube; d) computing (1008) an average particle velocity (Vij) over each section; e) computing (1010) a wave propagation speed (C2) of an antisymmetric wave (W2); f) based on the wave propagation speed (C2) and on the diameter (D), assessing (1012) the shear elasticity modulus (μ) of the tube.

摘要： A focus measuring arrangement for ophthalmic examination comprises an infrared light source system (100), which directs infrared light to a pupil (152) of an eye (150) of a person (156) and forms a focusing pattern (130) of the infrared light on a retina (154). A receiving arrangement (102) apertures (120A, 120B) receives the infrared light of the focusing pattern (130) from the retina (154) through separate areas (122A, 122B) of the pupil (152). An image forming arrangement (104) causes the infrared light passed through the apertures (120A, 120B) to form an individual image (124A, 124B) of the focusing pattern (130) for each of the apertures (120A, 120B) in an image space (110) of the receiving arrangement (102), the image forming arrangement (104) causing an optical correspondence between the at least two apertures (120A, 120B) and the separate areas (122A, 122B) of the pupil (152). A detecting surface arrangement (106) is located at a non-zero distance behind the at least two apertures (120A, 120B) and the image forming arrangement (104) in a direction of propagation of the infrared light reflected from the retina (154) for receiving the infrared light passed through the at least two apertures (120A, 120B). A data processing unit (108) forms focusing adjustment information based on locations ((XA, YA), (XB, YB), (XC, YC)) of illuminated spots (126A, 126B, 126C) of the infrared light of the focusing pattern (130) on the detecting surface arrangement (106), and outputs the focusing adjustment information for further processing.
