| description | <p>In this paper an electric field sensor based on the electro-optical effect in Lithium Niobate crystal is studied. The electro-optically induced polarization modification in crystal has been described and the response analyzed for different crystal lengths and light source wave lengths. The study shows that as the crystal length increased the required electric field to produce a phase-shift equal p is decreased. The responsivity of the sensor for different ranges of the electric field to be measured has been calculated and it is found that the rate of change of the half of the phase shift with respect to the electric field <strong><em>d(</em></strong><strong><em>f</em></strong><strong><em>/2)/dE</em></strong> is equal to the responsivity of the sensor at the mid-point of the linear part of the light intensity response curve.</p> |
