Embodiment 1
[0031] Step 1, use milk, artificial sea salt and purified water to configure different water solutions: solution 1, solution 2, solution 3, solution 4; add solution 1 into the glass tank 6;
[0032] Step 2. Remove the 1 / 4 wave plate 5, adjust the polarizer to 0°, turn on the laser, and the device emits 0° linearly polarized light;
[0033] Step 3, turn on the optical power meter 10, measure one path of outgoing light from the energy splitting prism 7, and adjust the optical filter at the same time to ensure that the light intensity value of the other path of outgoing light is appropriate, and record the data at the same time;
[0034] Step 4: The other beam passes through the polarization beam splitter 8, and the photovoltage value V of the horizontal polarization P in the beam is measured by the photodetector I9 and the photodetector II11 P and vertically polarized S photovoltage value V S measurement, and use (V P -V S ) / (V P +V S ) to calculate the polarization degree ...
