Abstract
A full range complex spectral domain optical coherence tomography system based on spatial sinusoidal phase modulation is presented. The quadrature components of an interferogram are obtained by harmonic detection, and the complex-conjugate ambiguity, DC term and autocorrelation noise are eliminated through Fourier transform of the complex interferogram. A complex-conjugate rejection ratio of about 35 dB is demonstrated. In practical applications, high speed complex-conjugate resolved imaging can be performed by combining sinusoidal phase modulation with transversal scanning.
