[The restoration of the "double peak" in OCT images based on inverse Wiener].
It has been found that the high reflectivity film of the reference mirror in OCT may cause a socalled "double peak effect" in the result images. To eliminate this a restoration algorithm is proposed here. The method is based on the mathematical modals of the point-spread function of OCT with consideration of double peak effect. The power spectrum of the noise and signal are estimated by the average smooth periodogram method. An inverse wiener filter algorithm, which avoids the illness condition in common inverse filter, gives the final restored images. The algorithm is also capable of the image degrading recovery due to the aberration and the band-limited spectrum.
