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.

摘要

光学相干断层扫描数据的干涉合成孔径显微镜处理已被证明能够对传统上被视为失焦的平面进行计算聚焦。结果表明，图像的这种聚焦在傅里叶域数据采集产生的自相关伪像中也会产生散焦效应。这种效应通过实验和模拟得到了验证。
