We describe preliminary experimental results on the laboratory demonstration of a technique to detect an extrasolar planet using a rotationally shearing interferometer. We simulate a planet and a star in a laboratory solar system. It consists of two laser beams; each passed through a spatial filter, collimated and combined. We confirm the theoretical prediction that the on-axis star generates no fringes for any shear angle. The star generates a uniform wave front that is invariant to the shear angle. Additionally, we demonstrate that the off-axis planet produces straight fringes. Thus, the mere presence of fringes confirms the existence of a planet. Furthermore, we illustrate that the fringe density and their inclination increase with the shear angle in the rotational shearing interferometer. Therefore, the number of fringes and their direction may be changed from the Earth to confirm (or reject) the existence of a planet.

用于太阳系外行星探测的旋转剪切干涉仪：太阳系模拟器的初步结果

我们在实验室演示中描述了使用旋转剪切干涉仪检测太阳系外行星的技术的初步实验结果。我们在实验室太阳系中模拟行星和恒星。它由两个激光束组成。每个都经过空间滤镜，经过准直和组合。我们证实了理论上的预测，即在任何剪切角下，轴上恒星均不产生条纹。恒星产生一个不变的波前，该波前不变于剪切角。此外，我们证明了离轴行星产生直条纹。因此，仅存在条纹就证实了行星的存在。此外，我们表明，在旋转剪切干涉仪中，条纹密度及其倾斜度随剪切角的增加而增加。因此，
