Abstract

A signal-to-noise ratio (SNR) analysis is presented for optical coherence tomography (OCT) signals in which time-domain performance is compared with that of the spectral domain. A significant SNR gain of several hundredfold is found for acquisition in the spectral domain. The SNR benefit is demonstrated experimentally in a hybrid time-domain-spectral-domain OCT system.

摘要

本文针对光学相干断层扫描（OCT）信号进行了信噪比（SNR）分析，将时域性能与谱域性能进行了比较。结果发现，在谱域采集时，信噪比有显著提升，达到数百倍。在时域 - 谱域混合OCT系统中通过实验证明了信噪比提升的优势。
