Embodiment Construction
[0030] The present invention will be further described below in conjunction with specific embodiments.
[0031] like figure 1 As shown, the ultra-high-precision icing detection device described in this embodiment includes a broadband light source 1, a spectrum analyzer 2, a fiber coupler 3, a coated fiber 4, a fiber polarization controller 5, and a Optical switch 6 and three fiber probes 7, 8, 9. Wherein, the broadband light source 1 and the spectrum analyzer 2 are respectively connected to two ports a and b on the same side of the fiber coupler 3 through optical fibers; the coated optical fiber 4 is installed on the optical fiber polarization controller 5 and connected to the optical fiber coupling The input end of the optical switch 6 is connected to the d port of the optical fiber coupler (3), and the output end of the optical switch 6 is connected to the three fiber probes 7, 8, and 9.
[0032] The broadband light source 1 selected by the device of the present invention ...
