| Abstract | The results of developing a compact version of the Precision Laser Inclinometer (CPLI) with the reduced overall dimensions of 20 × 20 × 20 cm and weight of 10 kg are presented. Experimental data on detected angular oscillations of the Earth’s surface at the JINR site are obtained. The achieved sensitivity is 6 × 10$^{–11}$ rad/Hz$^{1/2}$ in the frequency range 1.4 × 10$^{–3}$–10 Hz. The CPLI can be used in modern physical experiments for seismic isolation of large-scale installations. Reduction of the impact of microseismic angular oscillations of the Earth’s surface on the sensitive elements of the VIRGO Interference Gravitational Antenna, the Large Hadron Collider, and NICA will increase the accuracy of the experiments. |
