SPECTRUM DOMAIN INTERFERENCE APPARATUS USING AN FIBER-FERRULE OPTICAL CAVITY AND THE METHOD OF THE SAME
摘要
The present invention provides a spectrum domain interface device and a spectrum domain interface device. The spectrum domain interface device comprises: a laser light source oscillating in a constant frequency band at constant longitudinal mode frequency intervals; a fiber-ferrule resonator for making light received from the laser light source penetrate selected longitudinal modes having a free spectral range greater than the longitudinal mode frequency intervals; an interferometer for making interference light having a light path difference caused by different light paths from the light received from the fiber-ferrule resonator; a spectrum analyzer for resolving and analyzing the interference light received from the interferometer according to frequencies; and a signal processing part for extracting the spectrum cycle of an interference signal according to the frequencies using the interference signal of the spectrum analyzer, and the light path difference received from the interferometer using the spectrum cycle.
