Acousto-optic modulator

The acousto-optic modulator comprises a housing, one side of the housing is provided with an external driving module, and the other opposite side of the housing is provided with a collimator; an electroacoustic transducer is mounted in the center of an inner cavity of the shell; the electroacoustic transducer is electrically connected with an external driving module; a collimator input end and a collimator output end which are arranged corresponding to the collimator are arranged at the two ends of the side wall of the shell; the collimator input end and the collimator output end are respectively arranged on two sides of the electroacoustic transducer; the top surface of the electroacoustic transducer is provided with a crystal and a triangular holophote. The collimator input end and the collimator output end are both installed on the side wall of the same side of the shell, light beam input and capture are facilitated, modulation of the collimator can be achieved through two times of reflection of the triang
