Zusammenfassung: | The invention discloses an adaptive aberration correction far-field reflection type Fourier lamination imaging method. The method comprises the following steps: controlling a camera to scan and collect six low-resolution sub-images corresponding to sub-aperture positions through a two-axis precision displacement table, calibrating the aperture shape and size of a system by using the shot low-resolution images, correcting the frequency domain positions of the sub-apertures by using a simulated annealing algorithm, and correcting the frequency domain positions of the sub-apertures by using a self-adaptive aberration correction Fourier laminated imaging reconstruction algorithm to obtain a high-resolution image. And meanwhile, an object and system pupil function is reconstructed to realize aberration correction. According to the method provided by the invention, the problem of poor imaging quality caused by system parameter errors, system instability, system aberration and the like can be solved, and the imaging |
