We propose a novel Fourier-domain comb interferometry applied for the single-shot tomography with a combination of the VIPA and CCD. VIPA outputs the frequency different OFCs whose peak interval depend on their output angle. Thus, the interference fringe along depth direction displays on a CCD surface dimension that corresponds to τ₀. It effectively means a single-shot measurement. In addition, linearity of the peak position depending on the output angle is simulated and experimentally clarified. As a result, we found the effectively linear range where no distorted image can be obtained and it is possible to expand the measurement range for depth direction of sample by use of higher-order interference with high energy utilization efficiency.
