【摘要】 在制作多色反射体积全息图时，由于化学处理导致的记录材料收缩，不仅改变衍射光的波长，也改变衍射光的角度，并且记录材料的收缩程度不同，衍射光波长和角度改变量也不同． 本文报道一种方法，即通过调节记录时的参考光入射角，修正全息记录和处理过程中产生的衍射光角度的偏离，使一块干版上记录的多色反射体积全息图在同一方向再现． 这种方法，还可应用于在处理过程中有厚度收缩的其他全息记录材料．更多还原

【Abstract】 The shrinkage of recording material does not only change reconstructed wavelength,but also vary reconstructed angle while multicolorful reflection volume is made When the shrinking quantity of recording material changes,the reconstructed wavelength and the reconstructed angle deviation change too In this paper,it is reported a method to correct the reconstructed angle deviation which resulted from the holographic recording and the processing by adjusting the incident angle of reference light The method reported herein is also applicable in the process of shrinkage for other recording materials更多还原
