KeangPo Ho, Hsi-Cheng Wang, Hau-Kai Chen, Cheng-Chen Wu

摘要:

时间分辨光学滤波(TROF)通过快速光电二极管和可调窄带光学滤波器测量频谱图或声波图。对于周期性信号,为了匹配声图,使用数值TROF算法来找到原始复电场或等效的幅度和相位。对于相位调制的光信号,TROF算法使用声图的凹坑和脊来启动。

英文摘要:

Time-resolved optical filtering (TROF) measures the spectrogram or sonogram by a fast photodiode followed a tunable narrowband optical filter. For periodic signal and to match the sonogram, numerical TROF algorithm is used to find the original complex electric field or equivalently both the amplitude and phase. For phase-modulated optical signals, the TROF algorithm is initiated using the craters and ridges of the sonogram.
