Claim 8:
9. The common beam scanning retinal imaging system according to claim 5, characterized in that, the biaxial scanning mirror is a two-dimensional scanning mirror for realizing the horizontal and vertical scanning of the light beam, or is a combination of two one-dimensional scanning mirrors wherein scanning directions of the two scanning mirrors are set to be orthogonal to each other for realizing horizontal scanning and vertical scanning of the light beam respectively, and the two scanning mirrors are connected by a transmissive telescope or a reflective telescope to achieve a matching of light pupils;
the first transmissive or reflective telescope is configured to connect the wavefront corrector to the biaxial scanning mirror to achieve a matching of light pupils, and has a magnification equal to a ratio of the light-transmitting aperture of the biaxial scanning mirror to the light-transmitting aperture of the wavefront corrector; and
the second transmissive or reflective telescope is configured to conjugatively transmit the exiting light of the biaxial scanning mirror to the first dichroic beam splitter.
