WebThe correction of wavefront aberration plays a vital role in active optics. The traditional correction algorithms based on the deformation of the mirror cannot effectively deal with disturbances in the real system. In this study, a new algorithm called deep learning correction algorithm (DLCA) is proposed to compensate for wavefront aberrations and … WebNishizaki et al. used CNN to exploit the image-based wavefront sensing technique, which was effective for the images taken under different conditions such as overexposure, defocusing and scattering . Hu et al. presented a learning-based Shack-Hartmann wavefront sensor to detect the high-order aberrations without image segmentation or … riding on the back of a truck

WebMay 24, 2024 · In this letter, we proposed a deep learning wavefront sensing approach for the Shack-Hartmann sensors (SHWFS) to predict the wavefront from sub-aperture images without centroid calculation directly. This method can accurately reconstruct high spatial frequency wavefronts with fewer sub-apertures, breaking the limitation of d/r 0 ≈ 1 (d is … WebApr 1, 2024 · Deep learning wavefront sensing. Opt.
