Abstract
Introduction. Disclaimer analog and switch to the principles of pulse modulation can significantly increase accuracy by using fiber optic sensors. Were developed precision optical fiber sensors of new class width modulation intensity flux of optical radiation.Main part. It consists of three sections. The first section is estimated effect of temperature on the performance accuracy of meters based on fiber optic sensors with pulse modulation. It is shown that the use of preventive measures and proper processing of signals in the fiber-optic sensors, temperature influence on the metrological parameters meters largely be compensated. The second section examines the impact of volatility period pendulum rotation sensor. It is shown that the introduction of special schemes correction element allows movement of the pendulum in this case ensures high metrological performance of meters based on fiber optic sensors with pulse modulation. The final section shows that the presence of natural gravitational background does not allow to explore on Earth is extremely achievable design parameters measuring devices of this class. This can be done only on the spacecraft in conditions of free flight./Conclusions. Taking precautions and proper processing of signals pulsed optical fiber sensors enables significantly to achieve the calculated values of metrological parameters measuring devices based on optical fiber sensors with pulse modulation and when used under normal terrestrial conditions. However, extensive research capabilities of metrological meters from these sensors may only be carried out on board the spacecraft, provided their free flight.
