  1. In the thesis, a signal processing scheme of polarization - insensitive fiber optic michelson interferometric magnetic sensor is described : making the interferometer work near the quadrature with closed loop controlling working point method, the fundamental frequency component of the magnetic field sensing signals can be detected to measure the input direct current ( dc ) magnetic field by phase sensitive demodulation

    本文主要介紹了偏振無關光纖michelson干涉型微弱磁場傳感器信號處理的方案:通過閉環控制工作點演算法使干涉儀工作在正交工作點處，再利用相敏檢波演算法提取傳感器輸出信號的基頻分量，以測量直流磁場的大小。
  2. In quantum states which have squeezing effect, one quadrature phase may have reduced quantum fluctuations compared with what the relative quadrature phase have in coherent states, which makes it applied widely in optical communication systems, and so on. therefore, squeezed state of the radiation field is still a central topic in quantum optics

    由於光場壓縮態在其某一正交分量具有比相干態更小的量子噪聲，因此，在實際應用中，如果用這一分量傳遞信息，則可得到比相干態光場更高的信噪比。
  3. If we can prepare a mode of the electromagnetic field in an appropriately squeezed state, it will allow one to tune the signal - noise ratios of its quadrature components : one of the quadratures can be used to absorb the inevitable quantum - mechanical " noise ", while the other one serves to transmit an extremely well - defined signal

    如果將電磁場的某一個模式制備在壓縮態，那麼就可以調節信噪比，使得一個正交分量可以用來吸收不可避免的量子力學噪聲，另一個正交分量用來很好的傳遞信號。那麼在量子電磁場中當系統的一些模式被制備在壓縮態時，就很有必要研究場的腔性質了。
  4. Finally, we use resonance fluorescence theory to study the quadrature squeezing spectra in the resonance fluorescence of a v - type three - level atom driven by a coherent field and coupled to a single - mode cavity. the influence on the squeezing spectrum caused by cavity - induced quantum interference is discussed

    本文還應用共振熒光理論，研究了一個置於腔中的v型三能級原子的共振熒光的壓縮譜，探討了腔誘導量子干涉對原子共振熒光相振幅的壓縮譜的影響。
  5. A study of the property of generalized nonlinear unequal - power nj - th power y - squeezing and nj - th power h - squeezing on a new type of multi - mode superposition state of the equal - intensity of symmetry superimposition state with distinguishable two quantum states light field. it was found that two quadrature phase - components of state always present cyclic - changed symmetry - complementary relation ; besides we can abtain that under the condition when nj = n, the result of document 26 and document 27 is only a special circumstance, but the result in this thesis is generalized appearance

    結果發現：態， v恩）的兩個正交相位分量的廣義非線性不等冪次n _ j次方y壓縮及n _ j次方h壓縮效應總是呈現出周期性的對稱互補關系：另外，文獻26及文獻27中的研究結果僅僅只是本文的一般性理論結果在壓縮次數n _ j = n （ j = 1 ， 2 ， 3 ， … ， … ， q ）這一條件下的特例。
