Flexible interference patterning is an important tool for adaptable measurement precisions. We report on experimental results of controllable two-photon interference fringes with thermal light in an incoherent rotational shearing interferometer. The two incoherent beams in the interferometer are orthogonally polarized, and their wavefront distributions differ only in an angle of rotation. The spacings and directions of the two-photon interference fringes vary with the rotation angle, as illustrated in three cases of two-photon correlation measurements in experiment.
灵活的干涉模式是实现自适应测量精度的重要工具。我们报告了在非相干旋转剪切干涉仪中用热光实现可控双光子干涉条纹的实验结果。干涉仪中的两束非相干光束正交偏振，它们的波前分布仅在旋转角上有所不同。双光子干涉条纹的间距和方向随旋转角度而变化，实验中进行了三种双光子相关测量的情况说明了这一点。
