Paper Abstract

A novel but brief method is developed for spectral domain optical coherence tomography(SD-OCT). This method is based on two mirror locales in both sample arm and reference arm, independent of a mercury argon calibration source, and then get the exact spectral distribution on the line array charge coupled device (CCD) through fitting and interpolation. The rescaling parameters is determined by a short time Fourier transformation(STFT) and a series of calculation. A SD-OCT system is set up. The signal-noise-ratio(SNR) of this system is experimentally found to be 51dB. Axial resolution is 8.5μm. Improved 3D image of human retain based on the proposed method is demonstrated.
