Abstract
A block diagram of the electrooptical Kerr transducer is presented in Fig. i. When there is no voltage at the terminals of the Kerr cell 3 the light from the source 1 passes through the polarizer 2 and is captured by the analyzer 4 that is orthogonal to the polarizer; consequently, the signal at the photomultiplier FEU output 5 is zero. Upon delivery of a voltage to the optically active fluid filling the cell, an induced birefringence occurs resulting in a change in the nature of light beam polarization, and therefore, in the appearance of a signal at the FEU output. The Kerr cell is ordinarily a flat capacitor, where the electrode dimensions are such that the edge effects (field inhomogeneity at the electrode edges) do not substantially affect the apparatus function of the transducer, and can, as a rule, be neglected. In this case the transducer apparatus function has the form [2]
