Study on the diffraction efficiency of refraction index phase modulation hologram
-
摘要: 首先推出折射率相位调制型全息光栅的衍射方程,由此说明衍射效率主要取决于调制折射率,且各级衍射光的衍射效率不同是多种原因造成的。并指出体积光栅效应对透射全息衍射效率是有贡献的,讨论了影响散射物体全息衍射效率的问题,最后指出在一般情况下,调制折射率是一个很小的量,化学处理对它起着关键性的作用。Abstract: First,this paper deduced the diffraction equation for refractive index phase modulation holographic grating,and pointed out that the diffraction efficiency was mainly influenced by refraction index modulation,and the diffraction efficiency of different levels came from many factors.The volume grating effect affected the diffraction efficiency of transmission hologram. This paper also discussed the factors that influenced the diffraction efficiency of scattering object,and proposed the amount of refraction index modulation was very small,the diffraction efficiency was mainly determined by chemical treatment.
