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

叙述了积分干涉计量原理，仅用一幅载频干涉图获全部位相信息。

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

针对任意向双轴晶体,计算了完整干涉图,反映了相位分布决定等色线、振幅分布决定消影规律。
