Abstract[English]
An optical device for capturing images of an eye of an individual, the optical device (102) comprising a first measurement channel and a second measurement channel. The first measurement channel (102-a) is configured to generate at least one first lighting beam directed toward the eye and along a first axis and to capture at least one first image of the eye when illuminated by the at least one first lighting beam. The second measurement channel is configured to generate at least one second lighting beam directed toward the eye and along a second axis separated from the first axis by at least 5°, for example at least 10° preferably at least 20° and to capture at least one second image of the eye when illuminated by the at least one second lighting beam. The first measurement channel (102-a) and the second measurement channel (102-b) are synchronized together.[French]
L'invention concerne un dispositif optique pour capturer des images d'un œil d'un individu, le dispositif optique (102) comprenant un premier canal de mesure et un second canal de mesure. Le premier canal de mesure (102-a) est configuré pour générer au moins un premier faisceau d'éclairage dirigé vers l'œil et le long d'un premier axe et pour capturer au moins une première image de l'œil lorsqu'il est éclairé par le ou les premiers faisceaux d'éclairage. Le second canal de mesure est configurée pour générer au moins un second faisceau d'éclairage dirigé vers l'œil et le long d'un second axe séparé du premier axe d'au moins 5°, par exemple d'au moins 10°, de préférence d'au moins 20°, et pour capturer au moins une seconde image de l'œil lorsqu'il est éclairé par le ou les seconds faisceaux d'éclairage. Le premier canal de mesure (102-a) et le second canal de mesure (102-b) sont synchronisés ensemble.
