Core Research Progress

Traditional Synthetic Aperture Imaging (SAI) is constrained by the wavefield synchronization of multiple devices, which hinders its practical deployment. This study proposes the Multiscale Aperture Synthesis Imager (MASI). Leveraging distributed coded sensors and computational phase synchronization technology, it breaks the diffraction limit of a single sensor without requiring overlapping measurement areas. Benefiting from the lensless architecture, the system realizes submicron-resolution imaging at an ultra-long working distance and 3D reconstruction within a centimeter-scale field of view, substantially lowering the barriers to the practical application of optical synthetic aperture technology.

Technical Application Value

This technology addresses the key difficulty in deploying traditional optical synthetic aperture imaging. Featuring lensless design, ultra-long detection range, large field of view and ultra-high resolution, it enables efficient long-range high-precision 2D and 3D imaging. Applicable to long-distance precision observation, microscopic inspection and 3D topography reconstruction, it presents a brand-new solution for the industrialization of scalable optical synthetic aperture imaging systems.
