We research the various index modulation methods and design the scanning device to realize the apodized exposure.
研究了光纤光栅不同折射率调制的实现方法，并设计研制了实现变迹曝光法的扫描装置。

Also, computer simulation is conducted to work out the contrast curve of scanning spots and the offset voltage across the modulation unit of the optical phased array.
最后通过计算机模拟计算，得出扫描点的对比度曲线以及相控阵调制单元上所加的补偿电压。
