The results show that the relative rotation about the position normal to groove can compensate the error caused by the relative rotation about the position normal to the plan of gratings . the relative rotation about the position parallel to groove can compensate the error caused by groove - width difference and the relative rotation about the position normal to groove or about the position normal to the plan of gratings can compensate the error caused by groove - width difference
研究结果表明：绕光栅平面内垂直于刻线方向的转角在一定范围内可以补偿绕光栅厚度方向旋转造成的误差；绕光栅刻线方向的转角可以补偿光栅常数不同造成的误差；绕光栅平面内垂直于刻线方向或绕光栅厚度方向的转角在一定范围内也可以补偿由光栅常数不同造成的误差。
