Abstract:In order to boost optical coherence tomography(OCT)research,Matlab and ActiveX control were employed in the development
of time-domain OCT imaging system. In the software,scanning module of system was used to perform depth scan in accordance with the
required timing and parameters. NI data-acquisition card was used to obtain OCT interference signal synchronously. OCT signals were
processed using some signal processing methods,including stationary wavelet transform denoising etc. The full width at half maximum
(FWHM)of the interference waveform was calculated to achieve the resolution of the developed OCT system. The processed OCT data
was reconstructed to 2D OCT images. The results indicate that the developed OCT system have been highly integrated with a friendly
interface and it is convenient for software maintenance and upgrade. Therefore,it can facilitate the research of optical coherence
tomography. The system could be recommended to use in non-destructive testing and evaluation of multi-layered thin films.
