Abstract: Method and system for tracking of acoustic vibrations of a structural element of the middle or inner ear with optical coherence tomography using an acoustic source configured to generate an acoustic stimulus to induce vibrations of the structural element; an OCT device configured to measure a measurement signal comprising vibrographic information representative for the vibrations of the structural element in a measurement direction and an optical tracking system arranged to measure a tracking signal representative for displacements of the structural element in at least a tracking direction perpendicular to the measurement direction.

Abstract: An eye measuring apparatus includes a stimulator including multiple stimulator light points for projecting a plurality of light rays onto a surface of the cornea of an eye; a camera system for capturing reflected images of the stimulator light points; and a computational unit arranged to analyse the posterior surface of the cornea and/or to obtain a characteristic of the eye on the basis of the reflected images. The control unit is arranged to activate subsequently different subsets of the multiple stimulator light points; and to carry out the following steps: selecting, for each of the different subsets of the multiple stimulator light points, at least one reflected image that corresponds with activation of the respective subset of the multiple stimulator light points, and combining the selected reflected images with each other to analyse the posterior surface of the cornea and/or to obtain the characteristic of the eye.

Abstract: A device to determine a state of the lacrimal layer of the eye includes at least one light source arranged to form a pattern of source points for projecting a plurality of light rays onto a cornea surface; a lens-camera system arranged to receive a respective plurality of reflected light rays reflected on the cornea surface, thereby forming a pattern of image points; and a computational unit arranged to determine on the basis of the image points the state of the lacrimal layer of the eye and/or to determine on the basis of the image points data representative for the state of the lacrimal layer of the eye and to provide the data representative for the state of the lacrimal layer of the eye to a user.

Abstract: An apparatus for observing an eye comprises an imaging device (9) that is provided with a magnification unit (11) and an observation unit (10). The magnification unit (11) has an objective lens (12) for receiving observation light rays from the eye. The apparatus includes an optical coherence tomography (OCT) system (15) comprising an OCT light source (16) for emitting OCT light, as well as splitting means (17) for splitting the OCT light into a reference beam and a sample beam. The OCT system (15) comprises transferring means (33) for directing the sample beam from the splitting means through the objective lens to the eye. The OCT system comprises an OCT module (19) that is detachably connected between the magnification unit (11) and the observation unit (10).
