Embodiment Construction
[0022] Such as Figure 1-4 As shown, a nearly 180-degree water body three-dimensional volume scattering function measurement system includes a computer 108, and is characterized in that it also includes a laser 101 placed in a cage structure, an off-axis parabolic reflector 102, an aspheric lens group, and a CMOS polarization-sensitive Camera 107; described off-axis parabolic mirror 102 and aspheric lens group and CMOS polarization-sensitive camera 107 are coaxial directions; described off-axis parabolic mirror sectional view is as attached image 3 As shown, the reflective surface 308 of the off-axis parabolic reflector 102 is the cross section of the parent paraboloid 301, the focus 302 of the off-axis paraboloid reflector 102 coincides with the focus 302 of the parent paraboloid 301, and the optical axis 306 of the off-axis paraboloid reflector coincides with the optical axis of the parent paraboloid 303 are parallel, and the off-axis angle 305 adopted by the off-axis parab...
