Findings

Experimental setup capable of testing light speed isotropy to 1 part in 10^8.

Potential to detect anisotropies in the one-way speed of light.

Framework for future high-precision tests of fundamental physics.

Abstract

An experimental setup capable, in principle, to test the isotropy of the {\em one way} propagation of light to 1 part in $10^8$ (or better), is suggested.
