这项工作的复杂主从(CMS)的方法,处理光谱的光谱域干涉测量设备的干涉仪输出,而不涉及傅立叶变换(FT)后的数据采集的性能进行评估。将CMS的可靠性和性能与传统的基于FT的相位校准和色散补偿(PCDC)方法进行了比较。我们证明,这两种方法提供了类似的结果,在分辨率和灵敏度下降。产生CMS结果所需的数学运算是高度并行的,允许实时,同时从干涉仪中的不同光程差的几个点传递数据,这是通过PCDC无法实现的。
This work evaluates the performance of the Complex Master Slave (CMS) method, that processes the spectra at the interferometer output of a spectral domain interferometry device without involving Fourier transforms (FT) after data acquisition. Reliability and performance of CMS are compared side by side with the conventional method based on FT, phase calibration with dispersion compensation (PCDC). We demonstrate that both methods provide similar results in terms of resolution and sensitivity drop-off. The mathematical operations required to produce CMS results are highly parallelizable, allowing real-time, simultaneous delivery of data from several points of different optical path differences in the interferometer, not possible via PCDC.
