    Abstract
  • Fiber optic gyroscope (FOG) can be affected greatly by temperature and vibration. The limitations of input channel depolarization scheme and full polarization maintaining scheme were analyzed. Then, a kind of micro integrative transceiver module was designed to integrate super luminescent diode (SLD) source, half transmission and half reflection glass slide, collimation lens, GRIN lens, PIN detector and field effect technology (FET) circuit. The system in package (SIP) technique was applied and the vacuum was created. The light propagation in vacuum didn-t produce birefraction. Thus, the system accuracy and liability effects caused by temperature and vibration were avoided and the whole performance of FOG was promoted. The Superlum Inc. SLD-57-HP type source model was created by beam scanner. According to Gaussian beam characteristic, the compact optical system was designed and the Fresnel reflection loss was analyzed. Then, the simulation was exerted by Zemax software. The results show the coupling efficiency is 38.98% which exceeds current 20% coupling efficiency.
