Paper Abstract

The resample of spectra which is essential for high-precision spectral-domain OCT data processing is sophisticated, and its precision is dependent on the method and equipment. In this paper, we proposed an OCT without inverse FFT. A series of reference spectra corresponding to different optical path length difference was used to convolve with spectra gotten by OCT to acquire time-domain tomography instead of inverse FFT, thus eliminating the resample of spectra. The reference spectra were calculated before imaging and corrected with correction spectrum from sample arm to compensate the influence of sample arm. Experiment was done with a mirror as sample and validated our setup.
