摘要	An inducible human eye accommodation fundus camera based on adaptive optics (AO) is designed, including diopter adjustment system, illumination system and the AO imaging system. By setting a target, the diopter adjustment system induces human eye accommodation and corrects primary aberration to make the residual aberration in the range of correction of AO imaging system. To eliminate the strong stray light caused by a cornea and to illuminate the eyeground uniformly, double-axicon is used to generate annular beam that the inner diameter can be changed continuously by adjusting the distance between axicon-lens to accommodate different eyes. Hartmann-Shack wavefront sensor is used as wavefront detector and deformable is used as mirror as the wavefront corrector in the AO imaging system. Simulation results show that the illumination uniformity at the fundus is up to 95%, and the modulation transfer function of every field is greater than 0.36 at cut-off frequency of 76 lp/mm with the distortion less than 1%. The system design meets the requirement and can image eyeground clearly on the condition that diopter ranges from -6D to +8D.
