Description

technical field [0001] The invention relates to a long-distance light source alignment device for an X-ray grazing incidence lens, and belongs to the technical field of X-ray optics. Background technique [0002] X-ray detection technology has broad application prospects in the fields of space-based astronomical observation, space environment monitoring, deep space exploration and navigation in the future. The X-ray grazing incidence lens can realize focused imaging detection of the X-ray band, which is a key link in the X-ray detection technology; when using X-rays to test and calibrate the grazing incidence lens on the ground, the primary technical problem is how to quickly align the grazing incidence lens at a long distance. Incident lens and light source? [0003] The difficulty of long-distance alignment between the X-ray grazing incidence lens and the light source lies in: [0004] First, due to the limitation of the optical grazing incidence principle, the grazing i...

Problems solved by technology

[0008] The technical problem solved by the present invention is: to overcome the deficiencies of the prior art, the present invention provides a long-distance light source alignment device for an X-ray grazing incidence lens, by setting a beam expanding laser, a two-axis attitude adjustment frame, a lifting translation tripod, The aperture diaphragm and the four-degree-of-freedom translation and rotation stage realize the high-precision alignment of the grazing incidence lens and the X-ray source, which solves the problem of low precision of the traditional alignment device; through the two-axis attitude adjustment frame and the lifting translation tripod Cooperating with the adjustment of the position and direction of the laser beam of the beam expander laser, the alignment cycle is greatly shortened, which overcomes the long time-consuming problem of the traditional alignment device; the position and attitude of the grazing incident lens are fine-tuned by the four-degree-of-freedom translation and rotation stage to achieve The technical effect of simplifying the alignment operation process makes up for the defect that the traditional alignment device is complicated to operate
