光频调制 meaning in English

ofm optical frequency modulation

The main results and creative points in the dissertation were as follows : a ) by means of studying on the fiber - optic hydrophones ’ tdm array based on phase generated carrier ( pgc ) demodulation with laser frequency modulation , the mathematic models were set up , used for theoretical analyses of noncoherent crosstalks in the system using low coherent laser and coherent crosstalks in the system using high coherent laser . the formulas calculating crosstalks were given , and the method measuring crosstalks was shown definitely
本论文的主要研究结果和创新在于: 1 、通过对基于光频调制pgc (相位生成载波)解调光纤水听器时分复用系统的研究,针对低相干光源的串扰强度迭加和高相干光源串扰的相干迭加,建立了理论分析的数学模型,得出了计算串扰的公式,明确了测试系统串扰的方法。
