We developed a prototype of a repetitive microgravity interferometer for the third-generation gravitational wave detectors. A repetitive microgravity interferometer is a low-frequency gravitational wave detector with repetitively free-falling mirrors whose distance is measured using a laser interferometer. We developed a clamp-release system that is necessary for realization of free fall. We invented a new data analysis method using a matched filter and verified its effectiveness. We also built a prototype detector where two metal spheres repetitively free-fall with a linear motor and the distance of the spheres is measured with a shadow sensor. We operated it, took data, and analyzed the data.

我们为第三代引力波探测器开发了重复微重力干涉仪原型。重复微重力干涉仪是一种具有重复自由落体反射镜的低频引力波探测器，其距离是使用激光干涉仪测量的。我们开发了实现自由落体所必需的夹具释放系统。我们发明了一种使用匹配滤波器的新数据分析方法并验证了其有效性。我们还构建了一个原型探测器，其中两个金属球通过线性电机重复自由落体，并通过阴影传感器测量球体的距离。我们操作它、获取数据并分析数据。
