摘要
简述了全息变间距光栅的几何理论，研究了不同记录参数情况下的刻线弯曲程度。给出了用于评价光栅刻线弯曲程度的表达式，并推导出了它的积分形式，使计算效率提高了2～3倍。结果表明：球面波与非球面波干涉得到的光栅线条并不一定比球面波干涉得到的线条要平直。
The geometric theory of aspheric wave-front recording optics was briefly described. The merit function of the curve tendency was derived. The integral expression of the merit function was also derived to improve the calculation efficiency, The calculation result shows that the latter efficiency is 2 to 3 times of the former. Design example of holographic VLS plane gratings is given to demonstrate the capability of our method, which indicates that the curve tendency is in very good agreement with the merit function.
