Abstract
The present disclosure includes systems and methods for capture a whole slide image of a sample. In exemplary embodiments, a camera is configured to capture a digital image of a sample. The system captures a bright field image of the sample, and captures a digital image of the sample illuminated from a first incident angle at a first wavelength and a second incident angle at a second wavelength. The system can determine whether the sample is defocused based on the transitional shift between a first wavelength channel and a second wavelength channel of the captured digital image. The system can determine the defocus distance based on the transitional shift and autofocus using the defocus distance such the bright field image is in focus.
