DVS Coherent Receiver feem ntau yog siv rau amplitude demodulation faib kho qhov muag fiber ntau vibration sensor (DVS) daim ntaub ntawv. Lub module muaj cov yam ntxwv ntawm siab SNR ntawm coherent detection, thiab cov teeb liab tso zis yog amplitude teeb liab.Intradyne Coherent Receiver tuaj yeem siv ncaj qha rau hauv DVS system yam tsis muaj kev hloov kho demodulation algorithm; Nyob rau hauv lub hauv paus ntawm coherent nrhiav kom tau nrog siab teeb liab-rau-suab piv piv, lub analog teeb liab yog denoised nyob rau hauv lub module kom maximize lub teeb liab-rau-suab nrov piv, uas yuav txo tau daim ntawv thov ntawm qhov system optical amplifier module thiab txo cov nqi system.
Khoom nta
- High SNR ntawm coherent nrhiav kom tau
- Siv ncaj qha rau hauv DVS system
- Tsis tas yuav hloov kho algorithm
- Tsawg suab nrov rho tawm fais fab mov
- Txo cov nqi kaw lus
Khoom siv
- Distributed teeb raws li amplitude
- Demodulation Fiber Vibration Sensing (DVS)
