Complex-conjugate-resolved Fourier-domain optical coherence tomography,
where the quadrature components of the interferogram are obtained by simultaneous
acquisition of the first and second harmonics of the phase-modulated interferogram, is
applied to multisurface test targets and biological samples. The method provides efficient
suppression of the complex-conjugate, dc, and autocorrelation artifacts. A complex-conjugate
rejection ratio as high as
