thickness fringe 中文意思是什麼

thickness fringe 解釋
厚度條紋
  • thickness : n 1 厚；粗；厚度；粗大。2 濃度，濃厚，黏稠。3 密度；稠密。4 模糊不清，多煙霧，混濁。5 愚笨；遲鈍...
  • fringe : n 1 （地毯等的）穗，須邊，流蘇；緣飾。2 （森林等最外面的）邊緣；〈比喻〉（知識等的）初步，皮毛。3...
  1. Each fringe is the locus of all points in the film for which the optical thickness is a constant.

    每一個條紋就是膜上一切光學厚度為常數的點的軌跡。
  2. These values were used to reduce the fringe orders to correspond to slices of uniform thickness.

    這些數值是用來對邊緣級數進行折算，以使之與均勻厚度的切片所相當。
  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。
