Abstract

Phase modulation of laser radiation using an auxiliary generator makes it possible to improve the accuracy characteristics of fiber-optic gyroscopes. The authors propose a method for generating a phase modulation signal implemented on the basis of a parallel architecture with the possibility of dynamically changing the signal parameters. A prototype of a compact embedded generator for generating signals with frequencies up to 2.5 GHz is presented. The generator is implemented on a field-programmable gate array, which ensured a compact design and made it possible to include it in the design of a fiber-optic gyroscope. The dynamic change of the generated signal is carried out using a personal computer using the developed specialized software that allows generating arbitrary waveforms. For the developed generator, the spectra of a sinusoidal signal and white noise are presented.

Keywords: arbitrary waveform generator (AWG), Direct Digital Synthesizer (DDS), FPGA, fibre-optic gyroscope
