Onboard 3D imaging solid state laser radar system

The invention discloses an onboard 3D imaging solid state laser radar system, and relates to the field of onboard laser radars. The system herein can address the technical problems of slow scanning, large size, low receiving signal to noise ratio and low safety factor of conventional mechanical scanning laser radars. The system herein includes a laser device, a plurality of TR assembles and a central processing unit. The laser device includes an optoisolator, a pre-amplifier, a beam splitter, a main amplifier array, and a beam expanding collimated light path. Each TR assembly includes a transmitting system and an echo receiving system. The transmitting system includes a unidirectional glass array and a liquid crystal polarized grating array. The echo receiving system includes an optical filter array, a gathering lens array photoelectric detector array and a plurality of playback circuits. According to the invention, a radar has no mechanical rotary parts, which can greatly reduce the size of a laser radar sys
