Omnidirectional Gravitational Wave Detector with a Laser-Interferometric Gravitational Compass

TL;DR

This paper proposes an enhancement to laser-based gravitational wave detectors by adding a non-coplanar mass, creating an omnidirectional gravitational wave detector capable of source localization and ambiguity reduction.

Contribution

It introduces a novel design inspired by the Szekeres-Pirani gravitational compass, enabling existing detectors to operate omnidirectionally with improved source pointing capabilities.

Findings

Enables omnidirectional detection of gravitational waves.

Allows for source direction determination.

Reduces ambiguous interpretations of signals.

Abstract

Based on the Szekeres-Pirani gravitational compass we suggest the addition of a fourth, non-coplanar mass/mirror to the presently existing laser based gravitational wave observatories, enabling them to operate omnidirectionally, to filter out ambiguous interpretations and to point out the direction of the gravitational wave source.
