In a Kerr 4 cell, under the action of high voltage, the plane of polarization of the light beam rotates, its passage from the laser passes through the first polarizer 3, the Kerr cell 4 and the second polarizer 5. The change in light intensity caused by this is recorded by the recorder 6, and the high voltage form -. oscilloscope. 10. High voltage parameters are determined by the readings of the recorder 6, and the oscillogram allows to eliminate the ambiguity of measurements when the Kerr cell is operating in a nonlinear part of its characteristics and to determine the polarity of the measured voltage
