Vibration Isolation of Precision Objects
The need for vibration isolation of precision and vibrationsensitive objects is increasing continuously. Vibration isolation systems must comply with contradictory specifications, such as requiring reduced stiffness of isolators for better isolation, but higher stiffness for better performance of the object. Recently, expensive active isolation systems have been used to resolve these contradict...

متن کاملHigh-precision absolute distance and vibration measurement with frequency scanned interferometry.
We report high-precision absolute distance and vibration measurements performed with frequency scanned interferometry using a pair of single-mode optical fibers. Absolute distance was determined by counting the interference fringes produced while scanning the laser frequency. A high-finesse Fabry-Perot interferometer was used to determine frequency changes during scanning. Two multiple-distance...
متن کاملHigh-precision Absolute Distance and Vibration Measurement using Frequency Scanned Interferometry
In this paper, we report high-precision absolute distance and vibration measurements performed simultaneously with frequency scanned interferometry using a pair of single mode optical fibers. Absolute distance was determined by counting the interference fringes produced while scanning the laser frequency. A high-finesse Fabry-Perot interferometer(F-P) was used to determine frequency changes dur...
متن کاملMeasurement Model and Precision Analysis of Accelerometers for Maglev Vibration Isolation Platforms
High precision measurement of acceleration levels is required to allow active control for vibration isolation platforms. It is necessary to propose an accelerometer configuration measurement model that yields such a high measuring precision. In this paper, an accelerometer configuration to improve measurement accuracy is proposed. The corresponding calculation formulas of the angular accelerati...
