  • Publication number: 20190056578
    Abstract: 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.

  • Publication number: 20160088205
    Abstract: Certain embodiments pertain to Multiplexed Fourier Ptychographic imaging systems and methods. In one example, the Multiplexed Fourier Ptychographic imaging system includes an LED array configured to illuminate a sequence of LED patterns for illuminating a sample being imaged. The system includes LED circuitry configured to independently control power to turn on multiple LEDs simultaneously in each LED pattern of the array. The system has a light detector that acquires a first set of lower resolution images of the sample each image acquired during exposure time during illumination by a unique LED pattern. The system uses the first set of lower resolution images to generate a second set of lower resolution images associated with each LED in the LED array and iteratively updates overlapping regions in the Fourier domain with the second set of lower resolution images to generate a higher resolution image.
