Abstract

The study presented in this article was aimed to construct an appropriate set of interferometric optical fiber sensors for recording rotational events with their parameter investigation. Presented systems apply the principle of the gyroscope in an open loop configuration, as well as an electronic system, involving specific electronic solutions. They have a wide measuring range both in domain of the signal amplitude (3∙10^-8 – 10 rad/s) and frequency [from DC to 328.12/n Hz (n=1, …, 128)]. They are portable and equipped with an additional independent power supply, as well as they are remotely controlled. To determine parameters of random errors, we applied the Allan variance analysis with Angle Random Walk and Bias Instability determination. Nevertheless, in this paper, we present results which indicate that the appropriate method of error estimating is significant, but environmental conditions are crucial.
