Based on the traditional flowmeter , a new type flowmeter is fablicated utilizing the features of the fiber2optic in fluid , in which the amplitude , phase or frequence of the light may be modulated.
利用光纤在流体中光的强度、相位、频率等受流量调制的特性，在传统流量传感器的基础上，可以制得新型的光纤流量传感器。
Directly modulated laser combining with phase modulator is adopted to produce large chirped light, which can be compressed by DCF to generate the optical pulse.
该方案采用直调激光器配合相位调制器产生大啁啾并由DCF压窄输出光脉冲。
