Paper Abstract

The paper proposes a kind of scheme that uses dual way to construct a differential type fiber gratings sensor and signal control method. The sensor utilizes cantilever structure to little answer sense and possesses better optical frequency heterodyne regulated performance via stepper motor modulation. The dual differential type phase-shifted fiber gratings can be convenient regulation and scans frequency to proceed to heterodyne laser communication. It is proved that the scheme possesses many excellent characteristics such as upper sensitivity, powerful anti-jamming capacity. The scheme enters into a new domain of laser atmospheric communication system signal demodulation.
