Depth-resolved whole-field displacement measurement using wavelength scanning interferometry

We describe a technique for measuring depth-resolved displacement fields within a 3-dimensional (3-D) scattering medium based on wavelength scanning interferometry. Sequences of 2-dimensional interferograms are recorded whilst the wavelength of the laser is tuned at constant rate. Fourier transforma...
