  1. The system designing of fvisar are discussed in detail in charpter three. especially, the quantitative analysis and simulation research of the velocity range, fringe constant selection and attenuation of fiber delay line are intruduced

    第三章對全光纖速度速度傳感器的系統設計做了詳盡的討論，包括系統光源的選擇、條紋常數分析、光纖延遲線的損耗對調制度的影響、光信號接收單元、數據處理單元。
  2. By digital weighted filtering, the analysis of fringe frequency is converted into the analysis of fringe modulation. and based on the correlation between local spatial frequency and the reliability of phase data, the correlation between modulation after digital weighted filtering and the reliability can be set up. thus modulation ordering at this moment is equal to reliability ordering, resulting in an optimized path

    數字加權濾波之後的調制度函數攜帶了條紋頻率的信息，因此數字加權濾波將對于條紋頻率的分析轉化為對于調制度的分析，且根據偏離條紋基頻的程度與位相可靠度之間的對應關系，可建立經過數字加權濾波之後的調制度函數與位相可靠度之間的關系。
  3. Two wedge interferometers are designed that the thickness of one is higher than the other. so when the incident coherent light through the interferometers can acquire two fringe patterns which having space shift, but the incident incoherent light only result in consistent intensity signal. through a differentiating amplifier, two signals subtract which can eliminate noise of background and result in higher contrast ratio fringe signals. this method largely improves the system and the ability of detection. the spacing of line fringes is a function of incident laser wavelength, by analyzing, we can extract the wavelength of incident laser. the optical unit analyzing and results also simulated with matlab

    當背景光入射時，直接穿過干涉儀，僅發生強度的衰減，在兩個探測平面上產生幅度基本一致的灰度信號，通過差分放大器，相消為零，從而抑制了背景干擾。當激光信號入射，穿過干涉儀時受到調制，在探測平面上產生干涉條紋。通過所設計的存在平均厚度差的雙楔形干涉儀，兩路干涉條紋圖案出現相對移位：在兩個探測平面對應的位置上，一路出現亮紋，另一路出現暗紋。
  4. In the experiments, the phenomenon of the fringe frequency doubled we observed, ha hind that the resolution of the optical feedback system we doubled and the sensitivity of din optical feedback system we also improved after the modes competition between both the polarized light beams

    結果表明，光回饋系統解析度提高了1倍，同時利用雙頻激光器兩垂直偏振光間的模競爭，使得倍頻條紋的調制幅度明顯增大，從而使得光回饋系統的靈敏度大大提高。
  5. Compared with mechanics - electricity feedback control method, laser diode feedback control method and optical bistable equipment control method, the circuit is relatively simple, furthermore, simply adjust the optical system to increase the number of pixel corresponding to the interference pattern width, which will promote the control precision of the system

    和已有的機電反饋控制方法、半導體激光器反饋控制方法、光學雙穩裝置控制方法相比，電路較為簡單，而且，簡單地調節光學系統使干涉條紋寬度對應的象素數增大，即可提高系統的控制精度。
