英文摘要Many precision measurements using rotating optical cavities have tight requirement on the level of a rotating platform on which the cavities are installed. We develop a single-stage tilt control system as one part of the experimental setup for testing Lorentz invariance using two optical cavities that are perpendicular to each other. Home built voice-coil actuators, together with a tilt sensor and control electronics, are adopted to simultaneously suppress the tilt of the rotating platform in two orthogonal directions. The large cross coupling between two orthogonal axes is observed, and its mechanism is examined. By adding a compensating weight, the loop instability resulting from the cross coupling is effectively removed. With the active control, the variation of the tilt around each of the two axes is reduced from the free-running value of +/- 30 mu rad to within +/- 0.2 mu rad, independently measured by using a second tilt sensor. This residual tilt has a component at the rotational frequency with an amplitude of 0.1 mu rad, which contributes a systematical offset of 1.8 x 10(-17) to the Lorentz violating parameter kappa(ZZ)(e-), estimated by assuming that the tilt sensitivity of the optical cavity is 1 x 10(-16)/mu rad. Further improvement is still possible by using piezo-electric actuators that exhibit higher resonant frequencies, a different approach that will suppress the residual variation of the tilt to within +/- 0.01 mu rad and allow a reduced systematical offset of 1.8 x 10(-18) for kappa(ZZ)(e-).
