A sighting device for an examination by in vivo tomography of an eye of a subject including a viewer controlled by a control system for displaying at least one moving target where the at least one moving target has at least one of a programmable shape and a programmable trajectory, and is visible by the eye of the subject during the examination period to allow the subject to fixate and follow the target with their eye.

Eye examination device by means of tomography with a sighting device

An in-vivo high resolution lateral and axial tomography system of the retina, is provided, including a Michelson interferometer, generating a tomographical image by full field OCT interference with Z sweeping, adaptive optical correction apparatus, correcting the wave fronts coming from and going to the eye, including a reference source, a deformable mirror and wave surface analysis apparatus, detection apparatus producing an image from an interferometric measurement using the OCT principle and apparatus for focussing the wave surface analyser. The apparatus for focussing are embodied and controlled, synchronously with the Z sweeping to force the deformable mirror to adopt an additional curvature, such as to combine the input light source and detection apparatus at a given depth in the retina.

High resolution laterial and axial tomography

A sighting device is provided for an examination of the eye, including at least one moving target with a programmable form and trajectory, the target being displayed on a visualisation unit, such as an appropriate screen and visible from both eyes during the examination. An in-vivo tomographical eye examination system is also provided, including: a Michelson interferometer, generating a full-field OCT image, adaptable optical apparatus, arranged between the interferometer and an eye for examination, achieving the correction of the wavefronts coming from the eye and also the wavefronts going to the eye, detection apparatus, arranged after the interferometer, permitting the interferometric measurement by the OCT principle without modulation nor synchronized detection and a sighting device, with at least one mobile target with a programmable form and trajectory, the target being displayed on an appropriate screen and visible from at least one of the eyes during the examination.
