  1. We have calculated and plotted the curves of the refractive index, group velocity index, lowest - order and second - order dispersion indexes as a function of wavelength. the lowest - order and higher - order dispersion - induced broadening and deforming of light pulses is analyzed for various pulse shapes, such as gaussian, super - gaussian and hyperbolic secant pulses

    給出了折射率、群速指數、低階和二階色散系數隨波長變化的關系曲線，研究了高斯脈沖、超高斯脈沖和雙曲正割脈沖等超短脈沖在clbo晶體中傳播時，由於低階色散和高階色散引起的脈沖展寬和形變。
  2. We can see from the formula 8 = ? 2 n d ( ne - n0 ) / x that the retardation will be independent on wavelength if the refraction indices have direct ratio to wavelength, then we will get the achromatic optical phase retarders

    根據關系式2 d （ n _ e - n _ o ）可知，如果材料的雙折射率與波長成正比，延遲量便與波長無關，即可獲得消色差相位延遲器。
  3. 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算了向列相液晶bl037盒中指向矢分佈的計算，根據指向矢的分佈情況得到了向列相液晶的雙折射率分佈和非常光通過液晶盒產生的相位延遲隨電壓變化;並在矩形光柵和正弦相位光柵的基礎上，分析了入射偏振光通過液晶電控光柵所產生的衍射情況。
  4. If a optical anisotropic medium wafer is put into the mid of a polarizer and a analyser, the spectral transmission of the optical system can calculated. the transmission is determine by the birefringence and the thickness of the medium

    對各向異性介質處于透光軸相互正交的兩個偏振片之間構成的光路，其光譜透過率與介質的延遲量有關，即與介質的雙折射特性和厚度有關。
