| Abstract: | By using a shorter Sangnae sensitive ring,the Re-entrant Fiber Optic Gyro (Re-FOG) makes the two counter-propagandizing lights re-enter the Sagnac sensitive ring before they interference with each other on the photo-detector. The principle of the Re-FOG was first reviewed. The communication interface of Re-FOG with navigation computer,which was extended with TL16C550,was presented. The experiment results show the data transfer between Re-FOG and navigation computer can be accomplished fast,smoothly and precisely by means of asynchronous serial communication with its frequency being 1 kHz. The bias stability of Re-FOG is about 4.5°/h. |
| Keywords: | fiber optic gyro(FOG) re-entrant fiber optic gyro(Re-FOG) asynchronous serial communication. |
