The paper reports a method and a spectropolarimeter for determining the polarization state of an emitted or reflected light in terms of its Stokes parameters.
The system can achieve the measurement of temperature, pressure, rotational speed and twisting moment, and prevent the damage of engine and ergograph from faults by the function of alarm processing.
Helioseismology has become a new tool for the study of the solar interior as well as one of the most important devices to determine the quality of the the input physics that enters the solar models.
