Experimental determination of the diffraction angle of volume holographic gratings under off
体全息光栅偏移布拉格角读出时衍射角的测定
The basis is that when incident polarized light gets through a liquid - crystal box , it ’ s first diffraction angle and optical intensity are controlled by periodic electric field
其原理为:入射偏振光通过空间周期电场作用下的液晶盒,一级衍射角和衍射光强受到电压的调制。
Numerical examples show that , pulse deformation and broadening , spectrum redshifting , narrowing and distortion take place with increasing diffraction angle in the near field , and the pulse form changes with propagation distance in the near field , but is preserved in the far field
数值计算例说明在近场随衍射角的增大会出现脉冲变形、加宽、谱红移、变形、变窄等特性，脉冲形状在近场随传输距离变化而变化，但在远场保持不变。
