The invention provides a fiber-optic gyroscope gain and polarity automatic test system and a method thereof. The test system comprises a data acquisition processor, a man-machine interaction liquid crystal screen, a fiber-optic gyroscope gain and polarity algorithm arithmetic unit and a power supply. The data acquisition processor stores gain and polarity measurement algorithm programs, and sequentially configures the gain and polarity measurement algorithm programs to the FPGA module of the tested gyroscope after receiving a test instruction sent by the man-machine interaction liquid crystal screen; and the data acquisition processor receives the gain and polarity measurement data of the gyroscope to be measured, stores and analyzes the data, and sends the result to the man-machine interaction liquid crystal screen for display. According to the invention, the gain and polarity test of eight gyroscopes at a time can be realized without depending on an external turntable or other test equipment ...

The invention discloses a reciprocal voltage/electric field sensor optical path system based on an electro-optical rotation effect. Sensitive measurement on voltage field change is realized by utilizing a tetragonal crystal system taking a PbMoO4 crystal as an example and the electro-optical rotation effect of a 4/m point group crystal. The integrated sensing unit comprises an optical fiber collimator, a metal electrode plate I, a sensitive crystal, a metal electrode plate II, a reflecting mirror, a ceramic base and the like, is a generating unit of an electro-optical rotation effect, and has an optical path adjusting function. The integrated sensing unit adopts an optical integration scheme, so that the reliability of the sensing unit is improved, the environmental adaptability of the scheme is effectively expanded, and the practicability is improved. According to the optical path system, the reciprocal design of an optical path is realized, and the measurement precision and the anti-interference ...
