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.

我们为第三代重力波检测器开发了重复的微重力干涉仪的原型。重复的微重力干涉仪是一种低频引力探测器，其重复自由下落后视镜的距离是使用激光干涉仪测量的。我们开发了一种夹具释放系统，这是实现自由跌倒所必需的。我们使用匹配的过滤器发明了一种新的数据分析方法，并验证了其有效性。我们还构建了一个原型检测器，其中两个金属球以线性电动机重复自由下落，并用阴影传感器测量球体的距离。我们对其进行操作，获取数据并分析数据。
