Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a wavefront-aware adaptive optical imaging system and an imaging method thereof. Background technique [0002] Wavefront-free adaptive optics is widely used in wavefront phase jumps, difficult to obtain beacons, faint targets and some special applications, such as: confocal microscopes, space targets, remote sensing, optical coherence tomography and other imaging applications; to achieve imaging Feedback correction of system optical errors and slowly varying wavefront aberrations, and high-resolution images are obtained. The speed of wavefront correction in non-wavefront-aware adaptive optics systems mainly depends on the wavefront correction algorithm and the frame rate of the far-field detection camera. When the system adopts a certain control correction algorithm, the wavefront correction iteration speed mainly depends on the far-field camera detection frame rate, tha...

Problems solved by technology

[0017] The disadvantage of the above-mentioned prior art is that it mainly faces the coupling of adaptive optics far-field detection and target imaging functions, that is, both target imaging and far-field detection are realized by system far-field and target cameras

[0018] The working mode of the camera is difficult to meet the requirements of large field of view, large target surface detection and adaptive optics high frame rate far-field detection for target imaging at the same time. more expensive

Even in applications regardless of cost, the large-scale images detected by the large target surface of the imaging camera will result in huge data processing requirements, which will pose great challenges to the data processing capabilities of the wavefront controller and the system data transmission bandwidth.
