Abstract
Resolution in optical coherence tomography is often degraded due to sidelobes of the point response. Frequently, the spectrum of the low-coherence source is unable to be changed to reduce sidelobes. We present a method that derives a space-invariant linear post processing digital filter that reduces the sidelobes in the reconstructed image while minimizing the increase in image noise. This method is demonstrated on the image of rat mammary tissue.
