摘　　要：In order to detect the aberration from a wide field of view（FOV） on the retina with adaptive optics, we present a multiple-object Shack-Hartmann wavefront sensor（MOSHWFS） design. The simulated results indicate that the wavefront from our MOSHWFS can be reconstructed for multiple objects, and the measurement error can be less than λ∕7 with an MOSHWFS with an FOV of 6.7°, for maximum eye aberration. The experimental result with two objects indicates that the measurement error can be less than λ∕14, with the root mean square of the reference wavefront as 0.798λ and 0.895λ, respectively.In order to detect the aberration from a wide field of view（FOV） on the retina with adaptive optics, we present a multiple-object Shack-Hartmann wavefront sensor（MOSHWFS） design.
