Embodiment Construction
[0031] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0032] Such as figure 1 , figure 2 The dual-mode switching system of the space coronagraph shown is used to switch between the self-calibration mode and the observation mode of the space coronagraph. The dual-mode switching system includes a self-calibrating light source switching device, an optical path switching device and a positioning device. The wavelength division multiplexer 1 in the self-calibrating light source switching device couples output fibers of multiple self-calibrating light sources into one optical fiber for beam output. This optical fiber introduces the calibration light source into the optical path of the space coronagraph through the optical fiber connector 5 . Multiple self-calibration light sources are switched on and off (when one self-calibration light source is turned ...
