This study introduces a novel vibration compensation method using Equilibrium Optimizer (EO) to improve atomic gravimeter accuracy in dynamic environments. The approach effectively reduces noise and enhances gravity measurements, outperforming traditional algorithms.
Area of Science:
- Geophysics and Quantum Metrology
- Advanced Sensor Technology
Background:
- Atomic gravimeters face accuracy limitations in complex environments due to vibration-induced noise.
- Vibration compensation is crucial for enhancing gravity measurement precision by correcting phase noise and improving fringe fitting.
Purpose of the Study:
- To develop and validate a vibration compensation approach for atomic gravimeters using Equilibrium Optimizer (EO).
- To accurately estimate the vibration transfer function of a Raman reflector for improved gravity measurements.
Main Methods:
- Utilized Equilibrium Optimizer (EO) to estimate the simplified transfer function model of a Raman reflector.
- Applied the estimated transfer function to correct interference fringes in an atomic gravimeter.
- Compared EO performance against Genetic Algorithm (GA) and Particle Swarm Optimization (PSO).
Main Results:
- The EO-based approach accurately restored Raman reflector vibration in complex environments.
- Achieved significant reduction in root mean square error (RMSE) during fringe fitting.
- Demonstrated faster convergence and superior optimization compared to GA and PSO, leading to more accurate gravity measurements.
Conclusions:
- The proposed vibration compensation method enhances atomic gravimeter accuracy in challenging conditions.
- This technique offers a valuable reference for deploying atomic gravimeters in diverse and dynamic environments.
- EO provides a more efficient and accurate solution for vibration compensation in atomic gravimetry.

Measuring Acceleration Due to Gravity
A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...
