A simplified model is discussed which has proved useful for estimating the operational benefits of active systems in actual applications and some examples of specific applications which are particularly well suited for active control technology are discussed.Abstract:
EVIS is the first commercial active vibration control system suitable for general purpose application. It's design closely follows the guidelines and principles described by Sandercock in the previous paper. We First present quantitative operating data For the system, and then discuss some of the unique qualitative aspects of that performance. Some examples of specific applications which are particularly well suited for active control technology are discussed. We have found that the usual models for understanding the operation of conventional passive vibration control systems are not adequate when considering the corresponding active systems. Therefore we discuss a simplified model which has proved useful for estimating the operational benefits of active systems in actual applications.© (1987) COPYRIGHT SPIE--The International Society for Optical Engineering.

Advances in optomechanics
TL;DR: Optomechanics involves maintaining the correct shape and position of surfaces in an optical system as mentioned in this paper, and is sometimes defined as being involved with the mechanical engineering aspects of optical systems.

Active microgravity vibration isolation using PVDF polymer piezoelectric actuators
TL;DR: In this paper, a laminated piezoelectric actuator mount was developed for microgravity isolation in low earth orbit, where the magnitude of the distorting forces is a millionth of Earth's surface gravity, a microgravity.

Passive and active seismic isolation for gravitational radiation detectors and other instruments
TL;DR: In this paper, passive and active methods for reducing the effects of seismic disturbances on suspended masses are described, with special reference to gravitational radiation detectors in which differential horizontal motions of two or more suspended test masses are monitored.
