Gravitational wave predicted by General Relativity is the transverse wave of spatial strain. Several gravitational waveform signals from binary black holes and from a binary neutron star system accompanied by electromagnetic counterparts have been recorded by advanced LIGO and advanced Virgo. In analogy to light, the spatial fringes of diffraction and interference should also exist as the important features of gravitational waves. We propose that observational detection of such fringes could be achieved through gravitational lensing of continuous gravitational waves. The lenses would play the role of the diffraction barriers. Considering peculiar motions of the observer, the lens and the source, the spatial amplitude variation of diffraction or interference fringes should be detectable as an amplitude modulation of monochromatic gravitational signal.

来自微透镜的连续引力波的波性质

广义相对论预测的引力波是空间应变的横波。先进的 LIGO 和先进的 Virgo 已经记录了来自双黑洞和双中子星系统伴随电磁对应物的几个引力波形信号。与光类似，衍射和干涉的空间条纹也应该作为引力波的重要特征而存在。我们建议可以通过连续引力波的引力透镜来实现对此类条纹的观测检测。透镜将起到衍射屏障的作用。考虑到观察者、镜头和光源的特殊运动，
