【摘要】：壓縮真空光輸入和平衡零拍探測(cè)可有效增強(qiáng)Sagnac效應(yīng),提高陀螺精度;考慮平衡零拍探測(cè)的相位精度與相位自身相關(guān),僅在某特定相位能達(dá)到最佳靈敏度,設(shè)計(jì)了一種基于光子計(jì)數(shù)法提取Sagnac輸出相位的方案,并利用貝葉斯理論估計(jì)相位.理論分析結(jié)果表明,該方法能突破散粒噪聲極限,相位精度不再受限于相位自身,且當(dāng)壓縮真空光和相干激光功率相同時(shí),精度在理論上能達(dá)到海森堡極限.
[Abstract]:Compressed vacuum light input and balanced zero-beat detection can effectively enhance the Sagnac effect and improve the precision of gyroscope. Considering that the phase accuracy of balanced zero-beat detection is related to the phase itself, and the optimal sensitivity can be achieved only in a particular phase, a scheme of extracting Sagnac output phase based on photon counting method is designed. The Bayesian theory is used to estimate the phase. The theoretical analysis results show that the method can break through the shot noise limit, and the phase accuracy is no longer limited by the phase itself, and when the squeezed vacuum light and coherent laser power are the same. The accuracy can theoretically reach the Heisenberg limit.
