Method and Device for Synthetic Light in Flight Imaging
This invention is a method that enables ‘light in flight imaging’ using only continuous wave (CW) lasers and an inexpensive off-the-shelf CMOS/CCD camera. This method exploits a specific algorithm that allows one to “computationally shape” the pulse via postprocessing in the computer. By freely controlling the phase and amplitude...

Method and Device for 3D Imaging and Imaging through Scattering Scenes
This invention describes a method to develop a computational camera that can image through dynamic scattering media with high resolution. The camera can create a synthetic hologram by combining light at two closely spaced optical frequencies to produce a low-frequency synthetic wave (beat wave), largely immune to the unknown scattering processes between...
