通过对色差的定量计算，表明在一定调制深度范围内不会发生编码混淆。
The computation of colour difference indicated that the encoding confusion did not show up when the modulation depth is in a proper range.
从而为优化菱体型相位延迟器的消色差性，扩大材料的选取范围提供理论指导。
So the theoretical basis is provided for optimizing achromatism of the rhomb-type retarder and the material selecting scope can be extended.
给出一种新的三元复合式消色差补偿器，该补偿器具有调节方便、精度高、在一定波长范围内消色差性能良好等优点。
As compared to common compensators, this compensator is convenient to operate, and has a high degree of accuracy and a good nature of achromatism.
