Research Interests

DISP uses joint design of physical sampling and digital processing strategies to develop high performance sensor systems. DISP builds instruments for visible, infrared, ultraviolet, x-ray, millimeter wave, terahertz, acoustic and ion imaging and spectroscopy. DISP has made particular contributions to the theory and practice of compressive measurement systems and to spectral imaging, holography and diffraction tomography, optical projection tomography and high pixel count cameras.
