Iris filtering synthetic aperture optical ultra-discrimination imaging method

The invention belongs to the high-resolution optical imaging technology field and relates to a pupil filtering and synthetic aperture optical ultrahigh-resolution imaging method. The method adopts the pupil filtering technology and the synthetic aperture optical imaging technology to conduct imaging detection to subjects, augment the vision field of an imaging system to achieve large-aperture or large working distance measurement through the synthetic aperture imaging technology, raise the resolution of a sub-aperture imaging system with an ultra-resolution pupil filter, and finally achieve the ultra-resolution imaging detection by a large-aperture optical system. The method can improve the resolving power of equivalent full-aperture imaging systems, and reduce the number of sub-aperturesin optical systems and the distance between the sub-apertures, so as to reduce the volume and the complexity of the systems. The method is applicable to high-resolution, large field angle, large working distance and large-ape
