We propose a novel approach to detect gravitational waves based on a semi-rigid detector. The approach relies upon the time delay that the light takes to travel from a fixed mirror at the end of a rigid bar to a nearby free mirror. We show that the dimensions of the experimental device can be shortened in comparison to the conventional ones based on two free mirrors.

引力波探测器的新设计

我们提出了一种基于半刚性探测器探测引力波的新方法。该方法依赖于光从刚性棒末端的固定镜子传播到附近的自由镜子所需的时间延迟。我们表明，与基于两个自由反射镜的传统设备相比，实验设备的尺寸可以缩短。
