Laser measuring ray machine system

The utility model provides a laser measuring ray machine system which comprises the following components: a laser transmitting assembly, a laser reflecting assembly, a telescope assembly and a laser detecting assembly. The laser transmitting assembly comprises a pulse semiconductor laser diode and a collimating lens. The laser reflecting assembly comprises a hollow reflector and a connecting device. The connecting device is connected with a hollow reflector and is provided with mounting interfaces which are respectively connected with the laser transmitting assembly, the telescope assembly and the laser detecting assembly. The telescope assembly comprises an optical telescope which is composed of a negative ocular lens, a lens barrel and an object lens. The laser detecting assembly comprises an narrowband filter sheet, a focusing lens and a photoelectric detector. The optical paths among the laser transmitting assembly, the laser reflecting assembly, the telescope assembly and the laser detecting assembly of the system are parallel optical paths. Through the mounting interfaces of the connecting device, which are respectively connected with the laser transmitting assembly, the telescope assembly and the laser detecting assembly, assembly mounting or replacement without accurate measurement and positioning is realized.
