complication of Fourier domain optical coherence tomography (OCT) methods, such as spectral domain and swept source OCT, is the complex conjugate ambiguity due to inverse Fourier transform of real-valued data. As a result, the image is symmetric to the zero plane, and only half of the theoretical imaging depth range is used to avoid overlapping "mirror images" that confuse the image. We have previously demonstrated harmonic detection in a video-rate spectral domain OCT system using a high speed line scan camera. Harmonic detection removes the complex conjugate ambiguity by providing the real and imaginary components of the spectral interferogram. In ...Read Full Article
