Abstract: The original mechanical reading dial is replaced by high precision angular transducer, silicon photovoltaic cells are used to receive the light intensity distribution, the angle sensor is used to receive the digital display changes electrical signals of the angle and intensity distribution of polarized light. Experimental apparatus of polarized light show visually the changes in light intensity waveform and digital readout. Meanwhile,the design of the experimental apparatus for polarized light measurement experiments can achieve high accuracy requirements.

Key words: polarized light, angle sensor, deflection angle, light intensity distribution
