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 present an experimental setup and a CUDA implementation for a practical real-time application of compressive focal plane array camera. The implementation allows successful reconstruction of SWIR images from highly undersampled measurements in real-time.

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).

Dual-wavelength digital holographic microscopy (DHM) can provide sub-nanometer resolution for sample profile characterization. We analyze the noise requirement for extension of the vertical measuring range and the noise suppression methods in DHM.
