Abstract: The present invention relates to the field of instruments for visualizing the inner structures of the human body, and in particular of the eye. More specifically, its object is an optical coherence tomography system and method of the “Fourier-domain” type with the removal of unwanted artifacts through digital image processing.

Abstract: The present invention refers in general to the measurement of aberrations of the optical system of a living being, in particular a human. More specifically, the invention refers to methods and systems for reconstructing a wave front and/or for building a refractive error map.

Abstract: The present invention relates to the field of instruments for imaging internal structures of the human body, and in particular of the eye. More specifically it relates to an optimized process and an optical coherence tomography system thereof to measure the distances between the eye interfaces that is, the corneal surfaces, the surfaces of the crystalline lens, the retina and so on. A tiltable selection means, e.g. a titable mirror, is used to switch between different optical sample paths having different lengths, such that information relative to portions of the sample at different depths can be collected.

Abstract: The present invention refers in general to the measurement of aberrations of the optical system (E) of a living being, in particular human. More specifically, the invention refers to methods and systems for reconstructing a wavefront (W(z,p)) and/or for constructing a refracting error map.

Abstract: An ophthalmic device and method actively correcting possible movement of the eye of a patient with respect to the correct positioning during the examination are described. An illumination light beam is provided, that passes through a cross-section of the anterior chamber of the eye to capture an image on the corneal vertex.

Abstract: Process and system for determining the topography of bioelectric response signals of a visual system including a patient's retina, optical nerve or a projection thereof at the level of the central cortex, following visual stimulation through a surface arranged in front of the patient's eye. An image which comprises a plurality of cells is displayed as stimuli, each cell being activated or deactivated according to a corresponding digital time function represented by a cyclical succession of binary m-sequences of duration (T) formed from a plurality of activation symbols (N). Symbols N have a duration (Ts), and the m-sequences of the various cells are obtained cyclically from a mother m-sequence. The process determines the total bioelectric response of the visual system. The response associated with each cell is determined by the total response of the visual system using a cross-correlation with a suitable translated version of a mother m-sequence.
