摘要:
Certain aspects pertain to ptychographic imaging systems and methods with convex relaxation. In some aspects, a ptychographic imaging system with convex relaxation comprises one or more electromagnetic radiation sources, a digital radiation intensity detector, and a processor in communication with the digital radiation detector. The electromagnetic radiation provides coherent radiation to a specimen while the digital radiation intensity detector receives light transferred from the sample by diffractive optics and captures intensity distributions for a sequence of low resolution images having diversity. The processor generates a convex problem based on the sequence of low resolution images and optimizes the convex problem to reconstruct a high-resolution image of the specimen. In certain aspects, the convex problem is relaxed into a low-rank formulation.
