Abstract: This disclosure discloses a method of creating a three-dimensional image of a sample using snapshot optical tomography. The method includes generating a plurality of beams incident on the sample simultaneously, acquiring a field image at a plane not conjugate to the sample plane using off-axis digital holography, extracting amplitude data and phase data for the field image, restoring the sharpness by backpropagating the field image using the extracted amplitude and phase data, acquiring a background image, extracting amplitude data and phase data for the background image, and reconstructing a three-dimensional image of the sample with the backpropagated field image and the background image. The method also includes arranging more than one imaging chains to remove the missing angle artefacts in optical tomography. Also disclosed are systems for performing the method.
