The diffraction phenomena and analysis of self - focus lens 自聚焦透鏡衍射現(xiàn)象及分析
Simulation of fraunhofer diffraction phenomenon by fft 的衍射現(xiàn)象計(jì)算機(jī)仿真
Therefore the ghost diffraction phenomenon is not an experimental evidence for quantum non - locality 由此可以斷定鬼衍射現(xiàn)象并不能作為量子力學(xué)非局域性存在的實(shí)驗(yàn)證明。
And the results show that slice muscle tissue can make the incident laser beam generate obvious diffraction phenomena 結(jié)果表明,激光束經(jīng)過(guò)肌肉組織后,能在遠(yuǎn)場(chǎng)處產(chǎn)生明顯的衍射條紋。
An experimental setup is presented in which the ghost diffraction phenomenon can be observed for two un - entangled photons in the same mode 摘要設(shè)計(jì)了一個(gè)實(shí)驗(yàn)裝置,經(jīng)理論計(jì)算表明,用此裝置進(jìn)行實(shí)驗(yàn),應(yīng)當(dāng)可以觀察到鬼衍射現(xiàn)象。
At the different recording angles , the raman - nath diffraction and bragg diffraction phenomenon are observed , respectively . then , the wavelength selectivity and the relationship of diffraction efficiency and polarization state are discussed when the recording angle of 60 ? formed by two writing beam 分別觀察到了寫(xiě)入光束夾角不同時(shí)光柵的拉曼-奈斯衍射和布拉格衍射現(xiàn)象,并對(duì)雙光束夾角為60時(shí)寫(xiě)入光柵的波長(zhǎng)選擇性及衍射效率與入射光偏振態(tài)的關(guān)系進(jìn)行討論。
Difference iterative method was used to estimate numerically director configurations in the nlc - bl037 cell in this paper . the refractive indices and phase retard of nlc in electric field was presented on the basis of the calculation of liquid crystal director distributions . then we analysed the diffraction phenomenon when the linearly polarized light was controlled by diffraction grating which was based on rectangular grating and sinusoidal phase grating models and we got it ’ s math model 。 finally we designed the nlc phase grating and we did the experiment to validate the theoretic calculation 文中利用差分迭代法計(jì)算了向列相液晶bl037盒中指向矢分布的計(jì)算,根據(jù)指向矢的分布情況得到了向列相液晶的雙折射率分布和非常光通過(guò)液晶盒產(chǎn)生的相位延遲隨電壓變化;并在矩形光柵和正弦相位光柵的基礎(chǔ)上,分析了入射偏振光通過(guò)液晶電控光柵所產(chǎn)生的衍射情況。
