摘要
本文提出了在平面全息光栅制作过程中精确判断线槽的新方法,指出了采用球面波获得直线形线槽的途径,对平面全息光栅光栅常数的检验精度给予了分析。结果表明。
This paper proposes a new method for accurate determining the grooves of the PHG during manufacturing. It presents a way to obtain the straight line grooves using spherical wave and dis- cusses the accuracy of the grating spaces of the PHG. The resu- lts show that the testing accuracy of the grating space and the linearity of the grooves will be greatly improved using this met- hod.
