Comparison of vibration measurement methods for FSO fixture

The article presents an analysis and comparison of methods for vibration measurement of Free Space Optic (FSO) communication terminal fixture. The purpose of gathered data is to improve algorithm for tracking and pointing the FSO. For it there were gathered and compared data from a three-axis accelerometer and a two-axis optic sensor. The obtained data from the measurement can be used to separate and compare the effects of vibrations and atmospheric turbulence on reliability and availability of the FSO link.
