The design and application of the measuring circuit of inductance sensor base on the soft digital phase sensitivity detection 基于软相敏检波算法的电感传感器测量电路的设计
Results show that the displacement sensor based on self - mixing interference has the same phase sensitivity as a conventional interferometer 并且推导出smi位移测量具有与双光束干涉测量相同的相位灵敏度。
We clarified that if the three - level atom and the two - mode cavity field are all in the coherent superposition state , the different transition processes interfere each other , the emission spectrum exhibits phase sensitivity . second , the phase properties of the two - mode su ( 2 ) coherent field interacting with a - type three - level atom and the two - mode su ( 1 , 1 ) coherent field interacting with two atoms are investigated 我们考察了双模su ( 2 )相干场与型三能级原子相互作用系统以及双模su ( 1 , 1 )相干场与双原子相互作用系统中双模光场的相位性质,证明了光场每个j迄凶博士学位论文docioraldisser ” i人lion
When the cavity field is initially in photon number state or mixed state , the emission spectrum of the two - level atom has nothing to do with the phase of the atomic dipole . if the cavity field is initially in the coherent superposition of photon number state , the emission spectrum of the two - level atom exhibits phase sensitivity . if a a - type three - level atom is initially in the coherent superposition of its two non - degenerate lower states , the emission spectrum depends on the phase of the atomic dipole 证明了初始时刻驱动场处于光子数态或者光子数的混合态时,二能级原子发射谱与原子偶极矩的相位无关,只有当驱动场初始时刻处于光子数的叠加态时,原子发射谱才依赖于原子偶极矩的相位;而初始时刻处于两个下能态相干叠加态的型三能级原子发射谱对原子初态的依赖关系却不受单模驱动场的影响。
