Abstract

The conceptual new design of the Precision Laser Inclinometer (PLI) is proposed and developed what resulted in creation of compact instrument for its possible use in a restricted vacuum volume of sensitive elements of Gravitational Wave Interferometric Antennas. It is shown that the use of a position sensitive method—the dividing plates method—for the detection of angular inclination of laser beams, allows to reduce the dimensions of the PLI to a cube of 11 × 11 × 15 cm³ or to a cylinder with a diameter of 15 cm and a height of 11 cm. The reduction of the dimensions results in a simultaneous increase of 1.9 times in the sensitivity of recording the angular inclinations of the earth’s surface.

紧凑型纳米弧度精密激光测斜仪—一种用于干涉重力天线角微震隔离的创新仪器

摘要

提出并开发了精密激光测斜仪（PLI）的概念性新设计，从而产生了一种紧凑型仪器，可用于重力波干涉天线的敏感元件的有限真空体积中。结果表明，使用位置敏感方法（分隔板方法）检测激光束的角度倾斜，可以将PLI的尺寸减小到11×11×15 cm ³的立方体或圆柱体。直径为15厘米，高度为11厘米。尺寸的减小导致记录地球表面的角度倾斜度的灵敏度同时增加了1.9倍。
