Paper Abstract

In many instances, mechanical vibrations, not atmospherics, are the dominant contributors to time varying optical tilts affecting both astronomical and terrestrial observations. We used a pair of inexpensive micromachined accelerometers placed on the secondary mirror mount of a 12' telescope, inferring angular deviations from twice temporally integrated acceleration signals. We then applied this result with appropriate gain to a feed-forward tip/tilt mirror correction loop with good results.
