On the other hand, the reconstruction of the SRT, on the basis of the Lorentz-Poincare scheme implies in an undetectable ether rest frame (non ether drift) at least in the first order [2].
Particularly, Silvertooth has claimed an experimental detection of the ether drift velocity using a device capable of detecting the beams arriving in opposite directions [23].
According to the theories that incorporate the length contraction principle (Einstein and Lorentz-Poincare theories), experiments where two orthogonal light paths are compared (two way speed experiments) like the Michelson-Morley interferometer and all variants are incapable of detecting the Earth's motion (no ether drift) due to the length contraction of the interferometer arm parallel to the direction of the Earth's velocity.
This prediction is in agreement with modern ether drift experiments in vacuum [36, 37], using two cavity-stabilized lasers and whose value is
