  1. 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,僅發生強的衰減,在兩個探測上產生幅基本一致的灰信號,通過差分放大器,相消為,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,在探測上產生干涉條紋。通過所設計的存在均厚差的雙楔形干涉儀,兩路干涉條紋圖案出現相對移位:在兩個探測對應的位置上,一路出現紋,另一路出現暗紋。
