The multi-scale retinal scanning imaging system (200) comprises, according to one example, a lighting and detection module (210) adapted for the emission of a lighting beam and the detection of a beam reemitted by the retina, a two-dimensional scanning module (231) of the illumination beam and the re-emitted beam, a first optical channel, called "wide-field" channel, and a second optical channel, called "small-field channel", for focus of the illumination beam on the retina and reception of the re-emitted beam by the retina. The "wide field" channel comprises a first optical system (205, 201) intended to combine, for example, a plane of rotation of the scanning module and the plane (17) of the entrance pupil of the eye (10). The "small field" channel comprises a wavefront correction device (250), a second optical system (257, 256, 253) for combining a rotation plane of the scanning module and the useful surface of the correction device wavefront, a third optical system, comprising at least a portion of the first optical system, allowing a conjugation between the useful surface of the correction device and the plane of the entrance pupil of the eye. The multi-scale retinal scanning imaging system further comprises at least one first optical feedback element (241) for sending the re-retracted beam to one and / or the other of the first and second imaging path, and intended to be positioned on the first imaging path, between the common part of the first and third optical systems and the scanning module, and on the second imaging path, between the common part of the first and third optical systems and the wavefront correction device. Le système (200) d'imagerie à balayage de la rétine multi-échelle comprend selon un exemple un module d'éclairage et de détection (210) adapté pour l'émission d'un faisceau d'éclairage et la détection d'un faisceau réémis par la rétine, un module de balayage bidimensionnel (231) du faisceau d'éclairage et du faisceau réémis, une pr
