Optical coherence tomography (OCT) suffers from random noises which degrade contrast of image, these noises can not effectively be wiped off by filtering technique. Characteristics of random noises were discussed and analyzed, noise influences were identified on image. The method of wavelet transform is presented for image denoising. The result shows that the method can reduce image noises.
