Abstract
The existing space situation awareness optical imaging system is limited by the satellite platform and optical system, and it is difficult to realize large aperture observation and multi-dimensional optical characteristics data acquisition for rapid target detection. Aiming at the problem that the sparse aperture system is difficult to achieve clear imaging in all depth of field, and the image quality degradation caused by the defocusing and dislocation of the object point and phase closure, the refocusing imaging technology based on light field modulation is adopted to expand the synthetic aperture to full depth of field, and effectively compress the amount of data.
