  • Systems and methods for structured illumination super-resolution phase microscopy
    Patent number: 9864183
    Abstract: Systems and methods for structured illumination super-resolution phase microscopy are disclosed. According to an aspect, an imaging system includes a light source configured to generate light. The system also includes a diffraction grating positioned to receive and diffract the output light. The system also includes a sample holder positioned to receive the diffracted light for transmission through a sample. Further, the system includes an image detector positioned to receive the light transmitted through the sample and configured to generate image data based on the received light. The system also includes a computing device configured to apply subdiffraction resolution reconstruction to the image data for generating an image of the sample.
    Type: Grant
