Multiple-object Shack–Hartmann wavefront sensor design for a wide field of view on the retina

【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.更多还原
