    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.

    摘要： In one aspect an imaging system includes: an illumination system including an array of light sources; an optical system including one or more lens arrays, each of the lens arrays including an array of lenses, each of the lenses in each of the one or more lens arrays in alignment with a corresponding set of light sources of the array of light sources; an imaging system including an array of image sensors, each of the image sensors in alignment with a corresponding lens or set of lenses of the one or more lens arrays, each of the image sensors configured to acquire image data based on the light received from the corresponding lens or set of lenses; a plate receiver system capable of receiving a multi-well plate including an array of wells, the plate receiver system configured to align each of the wells with a corresponding one of the image sensors; and a controller configured to control the illumination of the light sources and the acquisition of image data by the image sensors, the controller further configured to perform: an image acquisition process including a plurality of scans, each scan associated with a unique pattern of illumination, each of the image sensors configured to generate an image for a respective one of the wells during each scan; and an image reconstruction process during which the controller performs a fourier ptychographic operation to generate a reconstructed image for each of the wells based on the image data captured for the respective well during each of the scans.
