Systems and methods for performing downhole analysis within a well bore employ a swept source laser that can be sent downhole to generate high resolution images of the well bore. Various embodiments can also determine other physical properties of a below ground structure. The swept source lasers can create images using low-coherence interferometry or optical coherence tomography. Systems and methods may also be used to determine fluid flow rates towards the sensor at discrete points, such as individual perforations, by measuring the Doppler effect on the light back-scattered from the fluid. Fluid flow information could also be extracted by measuring the phase shift of the light between subsequent light scans if a phase sensitive detection scheme is utilized.
