Rigid beam incident reflecting several laser beams to the grating 翻译结果3复制译文编辑译文朗读译文返回顶部 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: ...
The present invention relates to a method of making a diffraction grating device, in which an optical waveguide is irradiated, by way of a phase grating, with light capable of inducing a refractive index modulation in an optical waveguide region of the optical waveguide so as to form a ...

2. When the laser beam is incident normally on the grating, the light waves pass through the slits or lines of the grating and undergo diffraction at each slit or line. 3. Each slit or line can be considered as a secondary source of waves, which emit secondary waves that interfere with...
A diffraction grating is optically coupled between the multiplex optical waveguide and the single channel optical waveguides for diffracting an optical signal between the receiving/transmitting end of the multiplex optical waveguide and the receiving/transmitting end of the single channel optical waveguide....

Here, we present a light source consisting of a series of LEDs, a planar reflective diffraction grating acting as a wavelength combiner, a launching lens and a light guide. The source is intrinsically multi-band, contains no mov- ing parts, and is small and inexpensive in comparison with ...
Six-degree-of-freedom displacement sensing method using a diffraction grating as a cooperative target A novel six-degree-of-freedom displacement sensing method utilizing typical features of a diffraction grating is presented. It employs a laser source, thre... JA Kim,KC Kim,EW Bae,... - IEEE...
总的来看,superposition是‘万物之源’,是出现双缝干涉条纹(double slit interference pattern)或者光栅衍射条纹(diffraction grating pattern)的根本原因。 所以,大家要好好掌握这个知识点哦。 想提升IG/ALevel成绩,【文蓝GCSE/IGCSE/A-level辅导...
