干涉图

We describe a subfringe integration interferometry for which the phase information is evaluated only from one interferogram.

叙述次条纹积分干计量原理，仅用一幅光载频干条纹获全部位相信息。

The conoscopic interference patterns of crystals are calculated for any orientation biaxial crystal, which include information of isochromatic curve and isogyre.

针对任意双轴晶体,计算完整偏光干,映相位分布决定等色线、振幅分布决定消光影规律。
