We propose to use alternate direction method of multipliers (ADMM), to improve computational robustness of Fourier ptychographic microscopy (FPM). This method is highly parallel so it can be run efficiently on GPU or distributed CPUs.

The light field describes the radiance at a point from a ray coming from a particular direction. A scene’s light field is calculated with rendering software to simulate images for camera lenses with different aberrations.

We formulate and solve computed tomography (CT) that contrary to traditional CT, intentionally includes all scattering events. This leads to estimation of chemical decomposition per voxel, and significant dose reduction per quality of recovery.

We report on a matrix approach of optical imaging that allows to overcome aberration and multiple scattering issues in microscopy. This allows in-depth diffraction-limited imaging of biological media over a wide field-of-view (FOV).
