Embodiment Construction
[0033] Such as figure 1As shown, the present invention includes fisheye optical lens 1, filter wheel (1) 2, LCVR (1) and (2) 3, polarizer (1) 4, macro optical lens (1) 5, CCD (1) 6. Telescopic optical lens 7, filter wheel (2) 8, LCVR (3) and (4) 9, polarizer (2) 10, macro optical lens (2) 11, CCD (2) 12, dual channel Image acquisition card 13, computer 14 and LCVR driver 15. Taking optical system channel one as an example, the channel for imaging and detecting sky light is taken as an example. The fisheye optical lens 1 images the sky light under the hemispherical field of view on its focal plane at one time, and passes through the filter wheel (1) 2. light sheet, to obtain the light of the corresponding spectrum, and then pass through two LCVR (1) and (2) 3 and polarizer 4, and then pass through the macro optical lens (1) 5 and finally image on the CCD (1) 6, and the The output image signal is transmitted to the computer 14 through the dual-channel image acquisition card 13...
