| titleOfInvention | Dual-mode switching system for space coronagraph and switching method thereof |
| abstract | The invention relates to the field of space coronagraphs, in particular to a dual-mode switching system for a space coronagraph and a switching method thereof. The switching system comprises a self-calibration light source switching device, a light path switching device and a positioning device. A plurality of self-calibration light sources in the self-calibration light source switching device are connected with a wavelength division multiplexer through optical fibers, and the wavelength division multiplexer is connected with an optical fiber connector. The optical path switching device is characterized in that a motor is connected with a worm, the worm and a worm wheel shaft are arranged on an outer frame, the worm wheel is arranged on the worm wheel shaft and meshed with the worm, an optical fiber fixing rod is arranged at the locking end of the worm wheel shaft, and an optical fiber connector is arranged on the optical fiber fixing rod. The encoder is connected to the positioning end of the worm wheel shaft. The switching method comprises the steps that an encoder obtains angle position information; rotating the worm wheel shaft to the position of a calibration angle, and calibrating the light path; when the worm wheel shaft rotates to the zero position, the starlight enters the space coronagraph. The invention provides a switching system with higher precision and reliability and smaller weight and volume by improving the structure. |
