DEVICE FOR DETERMINING electrooptic crystal electro-optic coefficients

摘要

An apparatus for determining the electrooptical crystal electrooptic coefficients intended for classification electrooptic crystals.; The technical result is to increase the accuracy of determination of the electrooptical crystal electrooptic coefficients.; An apparatus for determining the electro-optic coefficients of the electrooptical crystal comprises successively disposed and optically coupled with the source of radiation, a narrowband tunable filter, divider cube optically coupled with two identical optical branches, each of which comprises in sequence along the optical axis and is optically connected between a polarizer, analyzed electrooptical crystal tunable phase compensator raid analyzer system fotodetektirovan Ia, and a control unit, high voltage power supply and electromechanical turntable.; The axes of the first and second optical branches by a system of mirrors in the second optical branch perpendicular and intersect in the test electrooptic crystal, mounted on said turntable.; Each phase incursion tunable compensator, analyzer, and each photodetection system, and said turntable, narrowband tunable filter and a high voltage power source electrically connected to respective inputs and outputs of the control unit, high voltage power supply - with a test electrooptic crystal.
