In order to improve the performances of near ground ultraviolet communication system, one of the key problems is to study the technology of integrated optical system with lightweight, low cost, integration and high reliability. At first, from the point of designing the integrated optical system, the near ground ultraviolet communication system’s composition and working principle are briefly introduced. And then, the structure, material and alignment method of the integrated optical system are emphatically analyzed and discussed. At last, on the basis of summarizing the research situation of ultraviolet communication optical system at home and abroad, the development trend of ultraviolet communication receiving and transmitting optical system technology is prospected, which has a certain theoretical guidance and significance for the further research of the near ground ultraviolet communication receiver and transmitter integrated optical system.
