The invention discloses a wavefront-sensor-free adaptive optical correction method based on a model, belongs to the technical field of optics, and is used for solving the technical problems that an existing wavefront-sensor-free adaptive optical method depends on mode selection, and the number of iterations is large. The method comprises the steps: employing the reciprocal of the integral of the image power spectral density low-frequency space as the image quality evaluation function of an image; on the basis of an incoherent imaging system model, deriving a relation between an image quality evaluation function (a reciprocal of an integral of an image power spectral density low-frequency space) and a mode coefficient; introducing N + 1 times of bias, collecting N + 2 images to calculate animage quality evaluation function, calculating a mode coefficient according to the derived relation, and generating conjugate wavefront by a deformable mirror, thereby achieving the purposes of correcting aberration and improving image quality. The method is suitable for correction in any mode as a substrate, the number of iterations is small, and the system bandwidth can be greatly improved.
