In this paper we study the effect of diffraction on the performance of a miniaturized moving-optical-wedge interferometer. By using the Gaussian model, we calculate the degradation of the interferometer visibility due to diffraction effects. We use this model to optimize the detector size required to obtain maximum visibility and study its effect on resolution of Fourier transform spectrometers based on a moving-optical-wedge interferometer. A comparison between these effects in Michelson and wedge interferometers is also presented showing the advantage of the moving-optical-wedge interferometer in suppressing the diffraction effects with respect to the Michelson interferometer.
在本文中,我们研究了衍射对小型移动光学楔形干涉仪性能的影响。通过使用高斯模型,我们计算了由于衍射效应导致的干涉仪可见度的降低。我们使用该模型来优化获得最大可见度所需的探测器尺寸,并研究其对基于移动光学楔形干涉仪的傅里叶变换光谱仪分辨率的影响。还给出了迈克尔逊干涉仪和楔形干涉仪中这些效应的比较,显示了移动光学楔形干涉仪相对于迈克尔逊干涉仪在抑制衍射效应方面的优势。
