| Abstract: | A coniform linear component is make by the principle of acquiring interferometric fringe from monochromatic light through Fresnel biprism. A circle grating is make using the linear component and the making conditions and steps are given, The distribution of the light intensity is given. The efficiency of making circle grating improves and the cost decreases by using the method. The method is simple and has the advantages of low vagabond ray,large carved area, high groove density, worse image erasing, stable diffraction efficiency in wider spectral coverage. |
