QuoGkA - Quantum Sensing through Optical Integration for Gravimetry with Cold Atoms
Motivation
The QuoGkA project is a three-year long initiative aimed at developing a compact atomic gravimeter. This project leverages advanced optical integration and packaging to revolutionize the measurement of gravitational fields. The primary purpose is to transition gravimeter technology from laboratory settings to practical, field-deployable systems and testing on UAVs. This transition aims to enhance the capabilities of industries such as mining, underground resource monitoring, and navigation by providing precise gravitational measurements.
Implementation & Objectives
The projects objectives and goals are:
- Development of a Compact Atomic Gravimeter: Create a highly miniaturized gravimeter capable of precise gravitational field measurements.
- Optical Integration and Packaging: Utilize advanced optical integration techniques to reduce the size and enhance the robustness of the gravimeter.
- Field Deployment: Demonstrate the field application of the system, including its use on a UAV in preparation for airborne gravitational surveys.
For successful implementation, miniaturization of the laser system of an atom interferometer and its integration into a compact atom interferometer demonstrator is necessary, in addition the miniaturization of the physics packages and control electronics.
Perspectives
The gravimeter enables high-precision gravity measurements for carbon capture and storage injection validation, mining and resource exploration, subsurface groundwater monitoring, defence, and infrastructure assessment. Its compact form factor offers scalable, GPS-free sensing in remote areas with rapid deployment, making it ideal for dynamic field environments and long-term monitoring.
