This method has some characters : during recording of the transmissive holograms the holographic grating placed in front of the holographic plate closefittingly is used as a spectroscope. the transmissive wave is served as the object wave and the diffraction wave through the holographic grating or the deflective reflect wave produced by the silicon slice is served as the reference wave, therefore the hologram is named as self - reference image hologram. the recording results are the off - axis holograms and the twin images can be separated successfully
在記錄透射型全息圖時，將全息光柵緊貼置於記錄干板之前，而光柵起到了分光的作用，直透波作為全息圖的物光波，參考光是物光通過光柵后產生的衍射波；記錄反射型全息圖時將矽片置於記錄干板之後，利用反射矽片產生離軸參考光，因此系統僅需一束照明光束，參考光來自物光本身，因此稱之為自參考像全息圖。 -
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
文摘:首先推出折射率相位調制型全息光柵的衍射方程，由此說明衍射效率主要取決于調制折射率，且各級衍射光的衍射效率不同是多種原因造成的。
