Abstract

The invention discloses a laser transmission target and a laser alignment method. The laser transmission target of the present invention is characterized in that, comprises " V " font prism, rectangular parallelepiped prism, right angle triangular prism and CCD camera; The vertical plane M1, M6 that this " V " font prism is opposite is incident surface and exit surface respectively, and this The four slopes of the "V"-shaped prism are respectively marked as M2, M3, M4, and M5, wherein the vertical plane M1 intersects with the inside slope M2 and the outside slope M3 respectively, and the vertical plane M6 intersects with the inside slope M5 and the outside slope M4 respectively. Intersect; the slope of the rectangular prism is parallel to the slope M2 of the "V" prism, a plane of the cuboid prism is fixed parallel to the M6 ​​surface of the "V" prism, and the CCD camera is used to receive the light beam emitted from the slope M5 . The invention realizes the online synchronous alignment and real-time displacement monitoring of the equipment.

Description

technical field [0001] The invention belongs to the technical field of lasers, and relates to a laser transmission target and a laser alignment method. Background technique [0002] Due to its high brightness and good directivity, laser can be used for collimation of equipment. The principle of laser alignment: take the line connecting the energy centers of the laser beam as the reference line, the laser beam is irradiated on the target, the spot detector inside the target measures the position information of the target relative to the laser reference line, and the target is installed on the On the measuring device, the relative positional relationship between the devices can be obtained. For the alignment of multiple devices, laser alignment based on conventional targets uses the method of target movement measurement, that is, the target is placed on the current device to be aligned, the position of the device relative to the laser beam is measured, and then the target is ...
