We present <i>femto-photography</i>, a novel imaging technique to capture and visualize the propagation of light. With an effective exposure time of 1.85 picoseconds (ps) per frame, we reconstruct movies of ultrafast events at an equivalent resolution of about one half trillion frames per second. Because cameras with this shutter speed do not exist, we(More)
Once thought to be devoid of life, the ice-covered parts of Antarctica are now known to be a reservoir of metabolically active microbial cells and organic carbon. The potential for methanogenic archaea to support the degradation of organic carbon to methane beneath the ice, however, has not yet been evaluated. Large sedimentary basins containing marine(More)

How will the world look with a one trillion frame per second camera? Although such a camera does not exist today, we converted high end research equipment to produce conventional movies at 0.5 trillion (5&#183; 10<sup>11</sup>) frames per second, with light moving barely 0.6 mm in each frame. Our camera has the game changing ability to capture objects(More)
We introduce an interactive method to assess cataracts in the human eye by crafting an optical solution that measures the perceptual impact of forward scattering on the foveal region. Current solutions rely on highly-trained clinicians to check the back scattering in the crystallin lens and test their predictions on visual acuity tests. Close-range parallax(More)
We capture ultrafast movies of light in motion and synthesize physically valid visualizations. The effective exposure time for each frame is under two picoseconds (ps). Capturing a 2D video with this time resolution is highly challenging, given the low signal-to-noise ratio (SNR) associated with ultrafast exposures, as well as the absence of 2D cameras that(More)

Our new computational photography technique allows us to visualize light in ultra-slow motion, as it travels and interacts with objects in table-top scenes. We capture photons(More)
We present a novel imaging technique, which we call <i>femto-photography</i>, to capture and visualize the propagation of light through table-top scenes with an effective exposure time of 1.85 ps per frame. This is equivalent to a resolution of about one half trillion frames per second; between frames, light travels approximately just 0.5 mm. Since cameras(More)
A study was conducted on physico-chemical parameters and heavy metal contents of water from the mangrove swamps of Lagos lagoon, Nigeria. The study was aimed at assessing its suitability for fish production and as well as its safety for drinking purpose in man. In all eleven (11) physical and chemical parameters and six (6) heavy metals were investigated(More)
