Abstract

The two-harmonic FD-OCT method, where the quadrature components of the spectral interferogram are obtained by simultaneous acquisition of the first and second harmonics of the phase-modulated interferogram, is used for complex-conjugate- resolved imaging of biological samples. The method is implemented using sampling of the phase modulated interferogram with an integrating detector array followed by digital demodulation at the first and second harmonics. A complex conjugate rejection ratio as high as 70 dB is achieved.
