The device for investigation of the phenomena of light polarization is shown in the Fig. 10.3.
Figure 10.3
1. Laser is the source of plane polarized light;
2. mirror is used for changing the direction of light propagation;
3. analyzer is polaroid used to study the polarized state of light;
4. photocell is registrated the intensity of the light, being transmitted through the analyzer;
5.ammeter is used to measure current intensity which appears in the photocell under the light effect.
It is necessary to rotate the analyzer and measure the current intensity, being shown by the ammeter. The current intensity is directly proportional to the light intensity.
