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

叙述次积干涉计量的原理，仅用一光载频干涉获取全部位相信息。

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

针对任意取向的双轴晶体,计算完整的偏光干涉,反映相位决定等色线、振决定消光影的规律。
