Verification of PSIM system based on tunable polarization light source
A tunable polarization light source with simple structures and good stability was developed to validate the feasibility of a Polarization Spectral Intensity Modulation(PSIM) experimental system designed by us. A glass stack consisting of two K9 glass pieces was mounted into the tunable polarization light source. By changing the tilt angle of the glass stack
the polarization degree of the partial polarization light output from the system could be adjusted. The working principle of the PSIM was derived
and the calculation method of polarization degree of the output light from the tunable polarization light source was obtained. On the basis of the principle of the PSIM system
a experimental device was built to verify the performance of the PSIM system. The measurement verification experiment was carried out in the laboratory and the different polarization degree spectra output from tunable polarization light source was measured. The results show that the error between the theoretical output of the tunable polarization light source and the measured results of the experiment equipment of PSIM is within 1% when the experiment equipment of PSIM works in its effective working wavelength range
which validates the feasibility of experiment device of PSIM and tunable polarization light source. Meanwhile
it verifies that the tunable polarization light source is expected to be a standard polarization light source and used in the calibration of polarization spectral measuring equipment.
