Summary
In this paper, a method for resolving three dimensional objects, at a timescale much faster than that achieved with confocal microscopy and for a much lower cost, is described. By using Fourier transformations and other mathematics, a three dimensional representation of a structure can be back-calculated by using the interference pattern generated by a laser shining through the sample. So, using this method coupled with a digital camera which can capture images at 30 fps, 3D reconstructions of particles in solution or other interesting materials can be created.
