Autocorrelation artifacts in optical coherence tomography and interferometric synthetic aperture microscopy

Opt Lett. 2007 Jun 1;32(11):1441-3. doi: 10.1364/ol.32.001441.

Abstract

Interferometric synthetic aperture microscopy processing of optical coherence tomography data has been shown to allow computational focusing of en face planes that have traditionally been regarded as out of focus. It is shown that this focusing of the image also produces a defocusing effect in autocorrelation artifacts resulting from Fourier-domain data collection. This effect is verified experimentally and through simulation.
