作者报告了宽带超连续光纤激光器(SCFL)用于光学相干层析成像(OCT)的适用性调查。从400 nm延伸到1800 nm的超连续谱光可以选择性地用于从600 nm到1700 nm的几个光谱波段,以便通过光谱和自相关测量、色散测量和图像采集来表征单模(SM)光纤OCT系统的性能。光谱选择和剪裁是通过带通滤光器的组合而实现的。此外,对于第一次,给定的光带宽可用,我们执行的有效噪声带宽的评估,考虑到平衡检测接收器中的分光器的光谱行为。
The authors report investigations into the suitability of a broadband supercontinuum fiber laser (SCFL) for use in Optical Coherence Tomography (OCT). The supercontinuum of light extending from 400 nm to 1800 nm can be used selectively in several spectral wavebands from 600 nm to 1700 nm in order to characterize the performance of single mode (SM) fiber OCT systems through spectral and auto-correlation measurements, dispersion measurements and image acquisition. Spectral selection and tailoring is made possible through a combination of bandpass optical filters. In addition, for the first time, given the optical bandwidth available, we perform evaluation of effective noise bandwidths which take into consideration the spectral behavior of the optical splitter in the balanced detection receiver.
由于平衡接收器的不匹配,光学相干断层扫描中可实现的信噪比受到限制。
