The first demonstration of optofluidic tomography is presented. Using partially coherent illumination, holograms of objects are recorded at multiple viewing angles, as they flow through a microfluidic channel placed directly on the top of an opto-electronic sensor array. These lensfree holograms are then digitally processed to compute pixel super-resolved tomograms of micro-objects to achieve sectional opto-fluidic imaging on a chip.
