We study the effect of diffraction on the performance of microelectromechanical system Michelson interferometers. By using a simple Gaussian model, we calculate the degradation of the interferometer visibility due to the diffraction effect. We then use this model to estimate the optimum detector diameter to maximize the fringe visibility at the interferometer output and study its effect on the resolution of Fourier transform spectrometers based on Michelson interferometers.
我们研究了衍射对微机电系统迈克尔逊干涉仪性能的影响。通过使用一个简单的高斯模型,我们计算了由于衍射效应导致的干涉仪可见度的下降。然后,我们使用这个模型来估计最佳探测器直径,以最大化干涉仪输出处的条纹可见度,并研究其对基于迈克尔逊干涉仪的傅里叶变换光谱仪分辨率的影响。
