  1. Compared with current instruments, the setup can decrease disturbance of disorder radiation by using double layer refractive index sample matching vessel, and it can increase collecting and transmitting efficiency of radiation by adopting single mode fiber with gradient refractive index lens. with a low power laser, the sample has a low scathe, and the laser and the measurement system can be integrated conveniently

    與現有的同類型儀器比,該儀器採用雙層折射率樣品匹配池減少了雜散擾;採用帶梯度折射率透鏡的單模纖接收、傳輸散射提高了散射的收集傳輸效率;用低強度的避免了對樣品的輻射損傷,同時可以使器和系統集成在一起,整個系統小型實用。

    基於鎖混頻原理的高精度外差的處理方法研究
  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

    當背景入射時,直接穿過涉儀,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,通過差分放大器,消為零,從而抑制了背景擾。當入射,穿過涉儀時受到調制,在探測平面上產生涉條紋。通過所設計的存在平均厚度差的雙楔形涉儀,兩路涉條紋圖案出現對移位: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。
