摘要
建立抛物柱面透射光栅的数学模型,由光程导出平行光通过单个抛物柱面的复振幅透过率,用傅立叶光学方法得出抛物柱面透射光栅在频谱面上的光强分布的表达式,利用计算机使用MATLAB语言模拟出其衍射光强的分布规律,得出的衍射花样与理论分析一致.最后讨论其在光学及其他领域的应用.
The mathematical model of the transmission-grating for a parabola cylinder was established. The complexamplitude transmission rate was obtained from the definition of an optical path when a parallel light passes through a singular parabola cylinder. By means of optical Fourier transform method, the expression of light intensity distribution in the spectrum was obtained for a transmission grating of a parabola cylinder. Using a computer, the distribution rules of diffractive light intensity were simulated based on the MATLAB language. The simulated results accord with the theoretical results. Finally, the application of the transmission grating for a parabola cylinder in optics and other field was discussed.
