求翻译：衍射光栅是一种能等宽等间隔地分割入射波前的、具有空间周期性结构的光学元件。主要分为两种光栅：透射光栅和反射光栅。刚光束入射到光栅面时反射出若干束激光，可形成扇形，星形等效果。是什么意思？

Diffraction grating is to divide the interval width, etc. before the incident, with periodic structure of the optical components space. Mainly divided into two gratings: transmission grating and reflection grating. Just when the beam incident to the grating surface reflecting a number of laser beams

Diffraction grating is one that would be divided into intervals such as bandwidth, such as radio wave-front of cyclical structure, with a space of optical elements. Two major types: TEM raster and reflective raster raster. Just beam shot into the raster-oriented reflection at a certain beam laser, c

The diffraction grating is one kind can wait for the width equal-space division incidence wavefront, to have the spatial periodic structure optics part.Mainly divides into two kind of diffraction gratings: Transmission grating and reflection grating.Just light beam incidence to diffraction grating s

Diffraction grating is a way to a fixed-width intervals such as segmentation, space-periodic structure prior to the incident wave optical components. Are divided into two kinds of grating: transmission grating and reflection gratings. Just beam incidence grating surface reflecting several laser beam
