We report on a test of Lorentz invariance performed by comparing the resonance frequencies of one stationary optical resonator and one continuously rotating on a precision air bearing turntable. Special attention is paid to the control of rotation induced systematic effects. Within the photon sector of the standard model extension, we obtain improved limits on combinations of 8 parameters at a level of a few parts in 10(-16). For the previously least well known parameter we find [EQUATION: SEE…

A review of one-way and two-way experiments to test the isotropy of the speed of light
As we approach the 125th anniversary of the Michelson–Morley experiment in 2012, we have reviewed experiments that test the isotropy of the speed of light. Previous measurements are categorized into
On the experimental determination of the one-way speed of light
In this contribution the question of the isotropy of the one-way speed of light from an experimental perspective is addressed. In particular, we analyze two experimental methods commonly used in its
