Method for the temperature-compensated, electro-optical measurement of an electrical voltage and device for carrying out the method |
摘要 |
For measuring an electric voltage in an electro-optic voltage converter, polarized light of two wavelengths is sent through a medium. At the output side, the light is led through a polarizer and the remaining signal is measured. For compensating a temperature dependence of the electro-optic coefficients, the measured results at both wavelengths are compared, and the voltage value consistant with both measurements is used.
