LIDAR TRANSMISSION/RECEPTION OPTICAL SYSTEM, LIDAR USING THE SAME, AND METHOD FOR

The invention belongs to the technical field of laser radars, and discloses a laser radar transmit-receive optical system, a laser radar using the same and a method for operating the same. The laser radar transmit-receive optical system comprises at least one transmit-receive module used for transmitting laser signals to the optical fiber coupling module or receiving reflected laser signals from the optical fiber coupling module. The optical fiber coupling module is used for transmitting the received transmitting laser signal to the conjugate system module or transmitting the reflected laser signal received from the conjugate system module to the transceiving module for processing; a scanning module; the conjugate system module is used for focusing an emission laser signal from the optical fiber coupling module to the scanning module or coupling a reflection laser signal received by the scanning module into the optical fiber coupling module, and the distance between a focus of a focusing system and the scanni
