Integrated interferometric optical gyroscope, assembly, system, and method for calculating rotation speed information

An integrated interferometric optical gyroscope, comprising a light source module, a first coupling module, a second coupling module, at least two polarization splitting rotation modules, a photoelectric detection module and a helical waveguide module, wherein

• the first coupling module is configured for splitting one beam of light waves emitted by the light source module into two beams of light waves;
• the two polarization splitting rotation modules are coupled to a telecentric end and a pericentric end of the helical waveguide module respectively, and configured for converting the two beams of light waves in a same TE polarization state into a TE polarization state and a TM polarization state, sending the light waves to two ends of the helical waveguide module to enable the light waves to be transmitted in opposite directions in the helical waveguide module respectively, then receiving the two beams of light waves passing through the helical waveguide module and converting the polarization states of the two beams of light waves back to the same TE polarization state;
• the second coupling module is configured for combining the two beams of light waves outputted from the telecentric end and the pericentric end of the helical waveguide module into one beam of synthesized light waves;
• and
• the photoelectric detection module is coupled to the second coupling module and is configured for acquiring rotation speed information of the gyroscope according to the synthesized light waves.
